It contains checking your area setup, sending behaviour, popularity historical past, engagement indicators, authentication, and even the sample of your sequence.

It’s that second if you suppose, “I wrote one thing good… so why did nobody see it?”

In the event you ship chilly emails usually, you already know this ache.

You write your sequence, plan your follow-ups, and hit ship. Now you look forward to replies.

However nothing is available in, and also you begin questioning whether or not folks ignored your e mail or by no means noticed it in any respect.

More often than not, the difficulty is just not your writing.

It’s the spam filters blocking your outreach earlier than it reaches anybody.

Why this occur (I’ve coated this later within the information).

On this information, I’ll clarify why good emails get flagged, what spam filters verify in 2025, the hidden set off factors that have an effect on your area, and the practices that assist your emails attain actual inboxes.

Allow us to get began.

What’s a Spam Filter and How Does It Work?

Fashionable filters use machine studying, Bayesian checks, blacklists, and sample evaluation to detect dangerous or undesirable emails.

After checking all these indicators, it decides the place your message ought to land.

Right here is how Spam Filters work:

• As soon as an e mail is obtained, inbox suppliers verify your authentication.
• They have a look at your SPF, DKIM, and DMARC information to substantiate the e-mail is real.
• Then the filters scan your content material. Inside content material, it appears for spam-triggering phrases, too many hyperlinks, or heavy attachments.
• Additionally they watch how folks work together along with your emails over time. In case your previous emails had low engagement, it impacts the subsequent ones too.
• All these checks create a spam rating. If the rating goes excessive, your e mail goes to spam or will get blocked utterly.

Why Even Reputable Emails Get Flagged as Spam

Listed here are the commonest causes (and how one can repair every one).

1. Poor Sender Status
2. Excessive Grievance Price
3. Weak E mail Authentication
4. Unverified E mail Handle Listing
5. Deceptive Content material

1. Poor Sender Status

Your sender popularity is like your credit score rating for e mail. 

The sender popularity tells e mail suppliers how reliable your area is. And whether or not your emails deserve to achieve the inbox.

In the event you ship too many emails from a brand new area or use unverified contacts, your popularity drops.

Bounces make it worse. As soon as your area’s popularity declines, even real emails can land in spam.

E mail suppliers observe: 

• What number of emails you ship
• How many individuals open your emails
• How usually you obtain replies

These indicators determine whether or not your subsequent e mail reaches the inbox or not.

A sudden improve in e mail sending quantity or low engagement makes your area look suspicious.

2. Excessive Grievance Price

Spam complaints normally come from a foul expertise. You already know the sensation if you wish to verify one essential e mail, however undesirable messages fill the display screen (The identical goes to your prospect!).

If recipients report your emails as spam, it’s apparent that the e-mail service suppliers will get direct indicators to think about your emails as spam. 

Even a small spam charge (round 0.1–0.3%, and Gmail’s 0.1% tolerance rule) can harm your area popularity and deliverability.

It normally occurs when your emails sound irrelevant or too promotional.

You’ll be able to verify your spam charge utilizing Google Postmaster Instruments.

It helps you see what number of customers marked your emails as spam in comparison with what number of you despatched to lively customers.

3. Weak E mail Authentication

In case your e mail is just not authenticated, it is going to go to spam.

With out SPF, DKIM, and DMARC, your area has no proof of possession.

Inbox suppliers deal with it like somebody is making an attempt to faux your identification, and so they block your emails to guard customers.

4. Unverified E mail Handle Listing

Sending emails to unverified contacts is the quickest approach to harm your area.

Even when your checklist appears positive, you by no means know what number of emails are inactive or invalid till you verify.

If you ship emails to such lists, most of them bounce again. As soon as that occurs, e mail suppliers begin doubting your area well being.

Why? 

Spam traps come in several sorts like pristine traps, recycled traps, and easy typo traps.

Many B2B databases nonetheless include these traps, even when they give the impression of being dependable from the surface.

And if you scrape information at scale, the possibilities of hitting these traps go up quick, which ends up in throttling and area points.

They assume you might be sending emails with out checking the standard of your checklist.

That’s how your deliverability drops, even when your marketing campaign is well-written. All the time confirm your checklist earlier than sending any chilly emails.

It helps you take away faux, outdated, or misspelled addresses that may have an effect on your sender popularity.

You need to use any good verification instrument to wash your checklist earlier than each marketing campaign.

Additionally, keep away from shopping for or scraping e mail lists. They usually include previous or inactive contacts that harm your area.

5. Deceptive Content material

Deceptive content material hurts your sender’s popularity shortly. Spam filters discover when your topic line guarantees one factor and the e-mail says one thing else.

When your message feels exaggerated, folks lose curiosity. 

And when readers cease partaking, inbox suppliers push your emails down.

A couple of spam stories or a drop in engagement is sufficient to block your attain.

Preserve your message sincere and aligned so your emails keep trusted.

Listed here are some frequent errors to keep away from:

Additionally, maintain these factors.

• Inbox suppliers verify in case your e mail appears promotional based mostly in your construction and CTAs.
• Too many hyperlinks make your outreach seem like an advert.
• Overusing advertising phrases can push you to Promotions quick.
• Heavy HTML signatures do extra hurt than good.
• Too many pictures in comparison with textual content is one other crimson flag.

When readers really feel misled, they cease trusting your emails.

10 Greatest Practices to Keep away from Spam Filters

Let’s study one of the best practices intimately one after the other.

1. Use a Skilled Area and Arrange Correct E mail Infrastructure
2. Authenticate Your Emails and Domains
3. Construct and Keep a Sturdy Sender Status
4. Confirm and Section Your E mail Listing
5. Write Clear, Customized, and Non-Spammy Content material

9. Take a look at Your Inbox Placement Earlier than Sending
10. Monitor and Take Motion Primarily based on Engagement Indicators

1. Use a Skilled Area and Arrange Correct E mail Infrastructure

Once I ship chilly emails, I at all times use an expert area. You must, too. Free domains like Gmail or Yahoo create belief points and find yourself in spam.

Inbox suppliers depend on these checks. It is advisable to use separate domains for outreach to maintain your most important area protected.

For instance, saleshandy.io or saleshandy.co works properly in case your major area is saleshandy.com.

Create branded inboxes like jane@saleshandy.co. Generic ones like data@ or contact@ get flagged quicker.

Unfold your inboxes throughout completely different suppliers or IPs. It lowers the danger of every little thing getting blocked directly.

A easy and well-planned area setup helps your emails land higher and protects your popularity.

2. Authenticate Your Emails and Domains

Once I arrange a sending area, authentication is the very first thing I repair. You must do the identical. Inbox suppliers depend on these checks to substantiate that your emails are real. 

With out them, your area appears unverified and dangerous.

There are three information you want:

Add these information for each area you utilize for outreach. Your DNS or e mail supplier provides you with the values you want.

After setup, run a fast check utilizing instruments like MXToolbox. It takes a minute and saves you from surprises later.

With out these information, even authentic emails can get flagged as suspicious.

If you wish to go above and past, comply with these steps as properly. 

• BIMI exhibits your model brand in supported inboxes and provides belief.
• ARC retains your authentication legitimate when your e mail will get forwarded.
• DMARC ranges matter. “None” solely watches, “quarantine” filters failures, and “reject” blocks them utterly.
• Hosts like GoDaddy or Hostinger usually add incomplete DNS information, so it’s best to double-check every little thing manually.

As soon as authentication is full, check it utilizing instruments that confirm your setup. This makes positive each outgoing e mail passes validation checks.

Correct authentication builds belief and improves your inbox placement.

3. Construct and Keep a Sturdy Sender Status

Your sender popularity decides how inbox suppliers deal with your emails. Consider it because the belief rating tied to your area.

Inbox suppliers observe small indicators. If folks usually ignore or delete your emails, your rating drops. In case your sending sample appears uncommon, it drops once more. 

Even a number of spam complaints can push every little thing down quicker than you anticipate.

Here’s what I persist with, and it really works:

• Don’t preserve sending to individuals who by no means interact. Take away them early.
• Use multiple inbox. It retains your sending sample pure.
• Select a sending platform with a correct popularity. Unhealthy networks create points even when your emails are good.
• Even personalised e mail follow-ups make them look distinctive. It retains your emails wanting human.
• Preserve a fundamental on-line identification. Inbox methods have a look at your area presence as a belief sign.
• Monitor your inbox well being. If an inbox struggles, cease and repair it reasonably than pushing extra quantity.

Status improves slowly if you ship responsibly, and that’s what inbox suppliers anticipate from you.

4. Confirm and Section Your E mail Listing

Sending emails to unverified contacts is without doubt one of the quickest methods to harm your area. 

I’ve seen many individuals skip this step, and it at all times exhibits up later of their deliverability.

If you ship to a foul checklist, even a number of bounces or spam traps can undo weeks of fine exercise. Inbox suppliers begin doubting your area instantly. You don’t want that.

Here’s what I do, and it’s best to comply with the identical:

• All the time confirm your checklist earlier than each marketing campaign. (Not as soon as, however each time)
• Take away faux, outdated, or misspelled emails. They do nothing for you.
• Keep away from role-based emails like data@ or gross sales@ when attainable. They set off filters extra usually.
• Keep away from purchased or scraped lists. They appear tempting, however they injury your area long-term.

If you’re utilizing Saleshandy, you don’t want any additional instruments. The built-in e mail verifier checks your checklist earlier than you ship something. It saves time and protects your sender’s popularity.

Preserve your bounce charge low. Something above 3% hurts deliverability. A verified checklist retains your sending wholesome and offers your campaigns a greater probability.

As soon as your checklist is verified, section it.

Separate new prospects from older ones. Preserve individuals who opened in a single group and individuals who replied in one other. Your message for every group shall be completely different, and inbox suppliers decide up on this relevance.

When your information is clear and your segments are clear, you create regular engagement. And regular engagement is without doubt one of the strongest indicators that helps you land within the inbox.

5. Write Clear, Customized, and Non-Spammy Content material

Good chilly e mail content material is just not about fancy writing. It’s about saying the correct factor that feels meant for the particular person studying it.

Your first line ought to inform them why you might be writing. 

Be sure to don’t have lengthy intros, and at all times say no to writing “Hope you might be doing properly.” 

Be direct and are available to the purpose that connects you with prospects.

E mail personalization must be pure. 

Search for small particulars that make sense:

• Their function and the way they see issues
• A brand new replace, launch, or hiring transfer
• A submit they shared or one thing they talked about
• Use one small element as your opening context

For instance:

“I noticed your crew is hiring for outbound reps. This may assist them get began quicker.”

Join their scenario along with your motive for reaching out. Preserve it brief. Preserve it related. Share how somebody like them solved an identical downside. It provides weight with out sounding salesy.

Now, right here is the half many individuals miss in 2025.

• Inbox suppliers pay extra consideration to conduct indicators than your wording.
• They have a look at how folks reply, not how many individuals open.
• Reply intent issues greater than click on or open intent.
• In case your e mail results in a reply, inbox suppliers deal with it as a constructive sign.

If you’re in search of a approach to enhance your reply charge, verify this YouTube video.

Don’t fall into predictable patterns.

AI sample detection can block lookalike sequences in the event that they repeat the identical construction each time.

Change your sample. Typically write emails with context. Typically with a small statement. It retains your emails human.

Keep away from errors that immediately break belief:

As soon as a reader feels misled, the belief disappears. And when belief goes down, even your greatest campaigns wrestle.

General, Preserve your CTA easy. A one-line query works higher than pushing for a name. Make each follow-up really feel like progress.

6. Observe a Pure E mail Sending Sample

Many chilly emails fail due to how they’re despatched, not what they are saying. Inbox suppliers verify your sending conduct earlier than checking your content material. In case your sample appears automated, they cease trusting your emails.

Here’s what I comply with, and you are able to do the identical:

Preserve your e mail sending quantity regular

• Begin small with new inboxes (round 30–50 emails a day).
• Don’t all of the sudden improve the variety of emails despatched.
• In the event you leap from 50 to 300 in someday, it appears suspicious.

Schedule your e mail all through the day

• Don’t ship every little thing at one actual time.
• Human senders don’t fireplace all emails at 9:00 AM day by day.
• Slight timing variations make your exercise look pure.

And preserve this in thoughts for Gmail in 2025:

• Gmail now appears at if you ship, not simply what you ship.
• If all of your emails exit on the high of each hour, it appears automated. Gmail flags this very quick.
• Use small, random delays between sends to keep away from this machine-like sample.

Keep away from predictable spacing in your sequences

• Don’t use the identical gaps for each follow-up.
• A sequence like day 1 → day 3 → day 5 appears clear to you however robotic to inbox filters.
• Shift the spacing somewhat so it feels extra human.

Keep constant

• Keep away from lengthy breaks between campaigns.
• In the event you ship usually after which disappear for weeks, it hurts your area if you restart.

Use a number of inboxes the correct approach

• Cut up your quantity throughout inboxes.
• For instance, ship 50 from a number of inboxes as an alternative of pushing every little thing from one.

Automate safely

• In Saleshandy, you’ll be able to set timing gaps and sending limits.
• It retains your sending sample regular with out additional guide work.
• Plus, you may also verify the sequence rating of your e mail sequence.

A pure sending sample builds belief within the background, and that belief is what helps your emails attain the inbox.

7. Keep away from Monitoring Open Charges

I finished monitoring open charges a very long time in the past, and it’s best to do the identical.

There was a time after they meant one thing, however inbox suppliers now block or preload monitoring pixels. 

A 70% open charge as we speak may simply be methods scanning your e mail.

These pixels additionally have an effect on deliverability.

Inbox filters deal with them as monitoring parts and push your emails to promotions or spam. Even a single pixel can change how your message is judged.

The identical factor occurs with hyperlink trackers.

 Inbox suppliers usually see them as advertising hyperlinks, and so they push your emails into Promotions and even Spam.

In the event you want monitoring, use a customized monitoring area. It appears extra pure and retains your deliverability regular.

And go simple on UTM parameters. Gmail strikes a number of UTM-heavy emails straight to Promotions.

Preserve your hyperlinks easy. It makes your inbox placement a lot more healthy.

Here’s what I observe as an alternative:

• Replies that present actual intent
• Clicks on helpful hyperlinks
• Conversions that show motion

These numbers inform you what labored with out risking your inbox placement.

In the event you use Saleshandy, you already get correct engagement monitoring with out counting on open charges. You’ll be able to see replies, clicks, and outcomes clearly, with out including any dangerous pixels.

8. Add an Unsubscribe Hyperlink (and Keep Compliant)

Inbox suppliers discover the way you deal with people who find themselves not .

If you don’t give them an unsubscribe choice, the one button they are going to click on is “Report spam.”

And that one click on hurts your area greater than anything.

Right here is why the unsubscribe hyperlink issues:

• It stops spam complaints earlier than they occur.
• It offers your reader a clear approach to step out.
• It additionally exhibits inbox filters that you simply comply with protected sending practices.
• Plus, it’s required below legal guidelines like CAN-SPAM and GDPR.

And now there may be yet another factor to bear in mind:

• Gmail expects a easy, one-click unsubscribe for bulk senders.
• Including the Listing-Unsubscribe header helps inbox filters belief your e mail.
• Even a “Reply to unsubscribe” works as a transparent opt-out sign.

A couple of extra compliance fundamentals that truly make a distinction:

• Use an actual sender title and a working reply tackle. Inbox filters verify this as a fundamental belief sign.
• Add your organization title, web site, or crew identification. It retains your outreach clear.
• Add a bodily tackle in case your area requires it.

E mail solely related prospects. This aligns with GDPR’s “authentic curiosity” rule and reduces complaints.

Compliance is just not solely authorized.

It exhibits inbox suppliers that you simply ship responsibly.

Domains that ignore these guidelines get flagged quicker, even when their content material appears positive.

In the event you use Saleshandy, most of those items are dealt with robotically. You keep compliant with out altering your writing type.

A easy unsubscribe hyperlink and some fundamental checks preserve your campaigns protected, trusted, and deliverable for the long term.

9. Take a look at Your Inbox Placement Earlier than Sending

Earlier than you ship any marketing campaign, it’s best to know the place your e mail truly lands. Inbox, spam, or promotion.

Inbox placement testing helps you catch issues early, earlier than they harm your popularity or waste your effort.

Right here is why it issues:

• Even with good content material and correct authentication, emails can nonetheless slip into spam.
• Completely different suppliers behave in another way. Gmail, Outlook, and Yahoo don’t deal with your e mail the identical approach.
• Testing exhibits you the true placement throughout these suppliers earlier than you hit “ship.”

Here’s what I verify each time:

• Area popularity: See if there are any blacklist points.
• E mail content material: Examine if the topic line or hyperlinks set off filters.
• Placement throughout suppliers: Gmail, Outlook, Yahoo, and others that your viewers makes use of.
• Authentication: Be sure SPF, DKIM, and DMARC are passing.

Right here is how one can run these assessments:

• Use Saleshandy’s inbox placement check to see the place your e mail lands.
• Ship a check e mail to a seed checklist with completely different supplier addresses.
• Examine your spam rating utilizing instruments like MxToolbox.
• Repair the problems that present up, then ship your marketing campaign.

When must you check?

• Earlier than the primary marketing campaign from a brand new area or inbox.
• If you change your templates or technique.
• Now and again, simply to maintain issues wholesome.

Common inbox placement testing saves you from surprises and retains your campaigns performing properly.

10. Monitor and Take Motion Primarily based on Engagement Indicators

E mail deliverability modifications based mostly on the engagement of individuals along with your emails.

In the event you ask me, I verify indicators to know if one thing goes unsuitable earlier than it turns into a major problem.

What I observe usually:

• Bounce charge beneath 3 p.c
• Spam complaints beneath 0.1 p.c
• Reply charge throughout every sequence
• Unsubscribes that leap all of the sudden
• Area popularity in Google Postmaster
• Blacklist checks as soon as every week

If I face any of those points, I resolve them by following these strategies.

• Clear the e-mail checklist if bounces go up.
• Enhance focusing on if complaints begin exhibiting.
• Strive new topic traces if replies fall.

Small modifications on the proper time preserve your area wholesome and your inbox placement secure.
