12 Reasons Your Emails Go to Spam

Here are the most common causes of email deliverability problems, ranked by how often we see them.

1

Missing or Invalid SPF Record

SPF tells receiving servers which IPs can send email for your domain. Without it, your emails look suspicious.

2

No DKIM Signature

DKIM adds a digital signature proving your email wasn't tampered with. Major providers now require it.

3

Missing DMARC Policy

DMARC is now required by Google and Yahoo for bulk senders. Without it, your emails may be rejected.

4

IP or Domain Blacklisted

If your sending IP or domain is on a blacklist (RBL), many servers will automatically reject or spam your emails.

5

High Spam Complaint Rate

If recipients mark your emails as spam, your reputation suffers. Keep complaint rates below 0.1% (Google's threshold is 0.3%).

6

Poor Sender Reputation

Your domain and IP build a reputation over time. New domains, inconsistent sending, or past issues can hurt deliverability.

7

Spammy Subject Lines or Content

Words like "FREE", "ACT NOW", excessive caps, or too many exclamation marks trigger spam filters.

8

No Unsubscribe Link

Marketing emails must include an easy unsubscribe option. Google and Yahoo now require one-click unsubscribe for bulk senders.

9

Sending to Invalid Addresses

High bounce rates from invalid email addresses damage your sender reputation. Clean your list regularly.

10

Missing Reverse DNS (PTR Record)

Your sending IP should have a PTR record that resolves back to your domain. Many servers check this.

11

No TLS Encryption

Emails should be sent over encrypted TLS connections. Unencrypted email is increasingly flagged as suspicious.

12

Shared IP with Bad Senders

If you're on a shared sending IP (common with email services), other users' bad behavior can affect your deliverability.
