Hey mate
AWS SES bans fast if you blast heavy on day one even with a clean list. Their system flags
sudden volume spikes, low engagement, and high complaints automatically.
To avoid bans next time:
- Warm up slowly (start with a few hundred → scale daily).
- Use double‑opt‑in or highly engaged lists only.
- Keep bounce/complaint rates extremely low.
- Rotate domains + proper DKIM/SPF/DMARC.
And honestly, for bulk sending, SES isn’t the best choice look for a provider/seller that offers
pre‑warmed SMTP/ESP built for volume.
Hope this helps, bro!
