Why email deliverability is the #1 thing new SaaS founders get wrong
You spend weeks building the product. Days writing the launch email. Minutes clicking send. And then: nothing. Not even a bounce. Your email didn't reach anyone — it went straight to spam. Here's exactly why, and how to prevent it.
The 5 mistakes that kill deliverability before you start
Sending from a brand-new domain
ISPs assign trust scores to domains based on history. A domain registered last week has no history — which ISPs treat as a red flag. Your emails go to spam before anyone reads the subject line.
No SPF, DKIM, or DMARC records
These three DNS records tell ISPs that you are who you say you are. Without them, ISPs can't verify your identity. Spam rate: near 100%.
Sending to unverified lists
Even a 3% bounce rate can blacklist your domain. If your list includes invalid addresses, role addresses (info@, admin@), or spam traps, your sender reputation craters on the first send.
Starting on a shared IP
Shared IPs mean your reputation depends on everyone else sending from that server. One bad actor ruins it for you too — even if your list is spotless.
Sending too much, too fast
Jumping from 0 to 10,000 emails in a single send looks exactly like spam to ISPs. Volume spikes trigger automated spam filters even on clean lists.
The one mistake that's hardest to recover from
Getting banned. Most email platforms ban first and explain (maybe) later. Your account is suspended, your lists are locked, and you're back to zero — on a new domain, with no sender history, starting the warmup process from scratch.
MailRevamp's 3-strike policy is designed specifically for this: three escalating interventions with expert calls before any account action. You're never blindsided.
