What this message means
If you're seeing this message, you have a reputation problem — too many people have been marking your emails as spam:
Lots of messages from [yourdomain.com] were identified as spam in the past
When your domain gets flagged like this, your sender reputation is in the danger zone. It's time to act quickly: run a re-engagement campaign to win back inactive subscribers, remove bad or unresponsive email addresses from your list, and take steps to rebuild trust with the people who actually want to hear from you.
Why it happens
Gmail's spam filters might be catching your emails because of things like deceptive subject lines, or an unsubscribe link that's too small or hard to find.
When unsubscribing is difficult, recipients tend to take the easy route and hit "This is Spam" instead. Every time that happens, your reputation drops — and Gmail learns to send your messages straight to the spam folder.
Make it easy to opt out
Always tell recipients how to unsubscribe, even if it's just a simple line like "Let me know if you'd like to be removed from this list." People are often too busy or too embarrassed to ask, so they click "This is Spam" instead. Letting them know it's okay to opt out encourages many of them to do the better thing and simply ask.
How to avoid getting blocked
1. Watch your content
Skip the hype — no excessive exclamation marks or phrases like "You must read this" or "Don't miss out"
Don't use spam words
Don't hide links behind tiny images or use white text on a white background
Avoid emails that are mostly images
Don't use emojis
Avoid long links or shortened links
Keep your signature simple — don't overload it with images, phone numbers, or GIFs
2. Keep your list clean
Remove bouncing addresses right away; repeatedly emailing dead accounts hurts your reputation
Validate your lead lists before sending
Don't mix email marketing and cold outreach on the same domain
3. Get the technical setup right
Keep your limits on each email
Make your DNS records clean and properly configured
