Before building SendSurety, I asked this to ~40 founders and marketers. The answers were wild:

• "I watch open rates in Mailchimp" (lags by days, only catches spam after the fact)

• "I check MXToolbox manually sometimes" (no alerts, easy to forget)

• "We have someone on the team who just knows this stuff" (knowledge silo risk)

• A surprising number: "We don't, honestly."

If you run email-heavy workflows SaaS transactional, newsletters, cold outreach I'd genuinely love to know what your current monitoring setup looks like. No wrong answers.

Most SaaS founders discover their email deliverability is broken the worst possible way: a user replies saying "I never got my password reset" days after the damage is done.

I built SendSurety after going through exactly this. Our welcome sequence was silently hitting spam for 11 days. Open rates looked "low" but not alarming. It wasn't until a user explicitly told us that we dug in and found a blacklisted IP and a broken DMARC record.

The scary part: none of our ESPs (SES, Mailgun) alerted us. They just logged "delivered" because technically, they handed it off. What happens after that is invisible to them.
