Hey everyone! I'm experiencing a frustrating issue with my self-hosted email server. Despite having a perfectly set up SPF, DKIM (2048-bit), and DMARC that all pass verification, my emails always land in Gmail's spam folder. Other email providers like Outlook, Yahoo, and Proton accept my emails just fine, so I'm baffled. Here's what I've ensured:
- SPF, DKIM, and DMARC are all valid and passing.
- My DMARC policy is set to quarantine, though I've tried reject as well.
- My PTR record matches both HELO and EHLO.
- I'm clean; my IP isn't blacklisted on services like Spamhaus and Barracuda.
- My domain is over 20 years old.
- I'm sending directly from my IP without using a relay.
I connected my domain to Google Postmaster Tools, which indicates a 0% spam rate, yet real emails still go to spam. I also submitted escalation forms, but they were rejected due to insufficient traffic. I've verified all technical checks with Google Check MX and confirmed DKIM via my email headers.
Can anyone share their wisdom on how to resolve this issue without needing to send thousands of emails daily? Are there escalation options beyond the usual forms? Would using a dedicated relay just for Gmail, while keeping direct SMTP for other services, be beneficial or harmful? Thanks for any help!

Have you thought about checking other blocklists in addition to your IP? Sometimes blocklists like Spamhaus ZEN can still affect deliverability in mysterious ways. As for your email landing in spam, how are you determining that? Have you tried inbox delivery tests? Also, how many people have reported to you that your emails are going straight to spam?
I actually faced a similar issue. A few thoughts:
- What do your compliance results look like on the new Postmaster?
- What's your daily email volume?
- What kind of content are you sending?
- Why did you decide to self-host?
- Have you followed Google's requirements for email senders fully? Their guidelines can be extensive, so missing small details can lead to issues.
1. They rejected my escalation due to insufficient traffic. 2. I typically send 1-3 emails per day. 3. It’s just everyday personal and business exchanges. 4. Purely for the control; I love self-hosting! 5. Yes, I’m sure after extensive checking, but it hasn’t yielded results.
Gmail's spam AI considers more than just blacklists. Content is a huge factor. Be sure to include easy unsubscribe options and avoid clickbaity subject lines. Also, remember that certain commercial email regulations apply, like including a physical address.
Exactly! The complexities of Gmail's filtering make it tough. I think for you, a reliable SMTP might actually help shift your emails from spam to inbox, while you build up a good reputation over time.
1. Yes, I've done extensive checks across multiple tools. 2. I've had confirmations from all recipients that emails are likely missing or landing in spam. I've even messaged some to check their spam folder after sending. It's a hassle! Currently, my routine includes texting friends to check their spam for my emails. I’ve created added measures like requesting they reply to me or mark my emails as important, but it only seems to work temporarily. I typically reach out to around 40 different people over the last six months.
