Best Practices for Deliverability – What Am I Missing? 🧐

Been in email for over a decade, and one thing remains true: respect the inbox!
💡 Be transparent – Clear subject lines & sender names build trust.
💡 Warm up new domains properly – Don’t just start blasting emails on day one.
💡 Avoid “graymail” – If users aren’t engaging, suppress them before ISPs do it for you.
💡 Always ask: Would I open this? – If the answer is no, it’s probably not a great email.

Mastering deliverability is a mix of tech and human behavior—balance both, and you’ll be golden! ✨

There should really be an awesome knowledge base article to concatenate all these answers that get posted! 

🚀 Great question! You’re spot on with SPF, DKIM, and list hygiene. I’d also add:
✅ DMARC – Helps prevent spoofing and builds domain reputation.
✅ Engagement-Based Sending – Prioritize active recipients and sunset disengaged users.
✅ IP & Domain Warmup – If you’re ramping up sending volume, do it gradually.
✅ Proper Authentication Alignment – Make sure your FROM domain matches your authentication settings to avoid mismatches.

Small tweaks can make a big difference! 🔥

Love this thread! Keeping it simple, here’s my golden rule for email deliverability: Send emails people actually want.

That said, here are my top non-negotiables:
✅ Permission-based sending – No shady list purchases, ever.
✅ Engagement matters – ISPs track opens, clicks, and replies. If people don’t care about your emails, neither will the inbox gods.
✅ Clean your lists – High bounce rates = bad news for deliverability.
✅ Less is more – Over-sending burns out your audience and your sender reputation.

If your emails are valuable, inbox placement becomes way easier. Quality > Quantity all day! 🚀

Oooh, my favourite topic! Here’s what’s worked for me:

• Avoid spammy words and phrases - words like “free”, “urgent” or lots of punctuation can trigger filters
• Use a custom return-path domain. Helps you boost sender reputation.
• Monitor blocklist - tools like MXToolbox can alert you if your domain has been flagged
• Set up BIMI! This displays your logo in the inbox, which helps with brand credibility.

I’m obsessed with tracking deliverability data!  Some key things I monitor:
 Inbox Placement Rates – Not just open rates, but where emails land (inbox vs. spam).
 Spam Complaint Rate – Keeping this below 0.1% is crucial.
 Engagement Segments – Filtering engaged users vs. dormant ones helps maintain a good reputation.
 Postmaster Tools – Google Postmaster & Microsoft SNDS give great insights into how ISPs view your domain.
Numbers don’t lie—data is your best friend in email deliverability!
