Spent way too long solving this so figuring I'd save someone else the trouble.
If you're doing cold outbound and running into AWS SES blocking your sends - that's not a config issue, it's their Acceptable Use Policy. SES explicitly prohibits unsolicited bulk email, no matter how you set it up.
The real fix is building proper cold-email infrastructure:
→ Buy dedicated sending domains (never your main company domain) → Set up SPF, DKIM, DMARC on each one → Use Google Workspace or 365 mailboxes, not rented/shared ones → Warm up every mailbox for 2-3 weeks before real sending → Rotate sends across mailboxes to keep per-inbox volume low → Monitor domain reputation ongoing
Shared/rented mailboxes are risky because you inherit whoever else is sending from them - one bad tenant tanks your deliverability with zero visibility into why.
Curious what setups others are running - Instantly, Smartlead, something custom?
