@kamilrextin The SDR cold email problem is real. Domain reputation is fragile and takes weeks to build back.

Separate question: are they sending from primary domain or do they use a subdomain like https://t.co/eSptYBG7zj? That separation helps a lot.

@benfitterman The list decay problem is real. Suppression lists aren't glamorous but they reset your engagement metrics. How do you handle re-engagement campaigns for that half that dropped off?

[DMARCflow @DMARCflow]

@ecomhoucem Love the analogy. One thing to add: even with SPF/DKIM/DMARC passing, bad domain reputation still gets you soft rejected. Google and Microsoft also check Postmaster data. Are you monitoring domain reputation separately from auth records?

[DMARCflow @DMARCflow]

@iamZenderock Forwarded mail is the hardest case. SPF was never designed for it. The forwarding server's IP breaks SPF at the destination. That's why ARC matters. Are you handling ARC?

[DMARCflow @DMARCflow]

@__Raiders Nice. TLS negotiation failures often get missed because they don't always trigger bounces. Just degraded delivery. What tooling do you use for the TLS side?

[DMARCflow @DMARCflow]

@JustenEcom What was the culprit? ESP migrations breaking DKIM silently is common. One vendor change and auth fails without any bounce.

[DMARCflow @DMARCflow]

@__Raiders Smart. What triggers your alerts? SPF/DKIM fail counts or also monitoring TLS delivery failures?

[DMARCflow @DMARCflow]

@ConradOutbound Nice thread. One thing I'd add: you mentioned SPF/DKIM/DMARC but a lot of people skip MTA-STS. Without it your mail can get intercepted in transit even after passing auth. Worth adding to your monitoring checklist.

[DMARCflow @DMARCflow]

@benfitterman Truth. Most people find out their rep is shot when cold outreach just stops working. Do you monitor Google Postmaster Tools at all?

[DMARCflow @DMARCflow]

@0Venkata The scary part is most teams never see it coming. By the time Postmaster shows Medium you've already been bleeding for weeks. The ESP dashboard doesn't tell you what Google knows about your domain. Are you checking Postmaster tools weekly?

[DMARCflow @DMARCflow]

@GetLeadsminer The 7.6% enforce stat is wild. Most people don't realize p=none is still useful. You get daily aggregate reports showing exactly who's forging your domain. That alone is worth setting it up.

[DMARCflow @DMARCflow]

@omranchi00 That's a brutal reality check. Greyhole is the worst because you never know it's happening. Which provider is your app using? Some have better spam filtering than others.

[DMARCflow @DMARCflow]

@0Venkata Auth setup gets you in the door. But engagement patterns determine inbox placement. Suppressing dead weight feels counterintuitive but the numbers say otherwise. Do you track engagement at individual or list level?

[DMARCflow @DMARCflow]

@tyronmm The complexity is real. But you don't need to understand all of it at once. Most people start with monitoring (p=none) and add strictness later. What email setup are you working with?

[DMARCflow @DMARCflow]

@Jtsternberg This is a sharp thread. The forwarding chain trace is exactly how you'd catch it in practice. DMARC alone can't protect against a legit message being relayed with malicious intent. What's your rule for flagging the account name field if it contains a phone number?

[DMARCflow @DMARCflow]

@wakwak_koba Exactly. When Rakuten rewrites the From header through their own servers, DKIM breaks and DMARC fails. It's a common issue with high-volume third-party email flows. Are you seeing this as a DMARC aggregate report finding, or as a direct mail failure?

[DMARCflow @DMARCflow]

@deckard_the_dev @venkatofl DKIM verified is step one, but the alignment matters too. Does your From domain match the DKIM d= domain? Also check if you have a DMARC record. Without it, Gmail guesses, and that often means spam.
