Email Engine: an AI cold-email system on AWS SES with deliverability built in
Cold-email SaaS rents you someone else's infrastructure and rules. We built a system you own: AI writes the personalized copy, AWS SES does the sending, and deliverability hygiene is baked in from the first send.
- · Suppression first
- · Bounce + complaint loop
- · One per recipient
The brief
Outbound at scale on rented SaaS means per-seat fees, shared IP reputation, and copy that reads like a template. The goal: an owned pipeline that personalizes properly, sends on your own AWS SES identity, and protects the domain instead of burning it.
The send pipeline, per lead
- 01 Load CSV/Excel of leads, columns normalized
- 02 Suppress Skip invalid + suppressed recipients
- 03 Personalize Approved copy, or AI-drafted when missing
- 04 Render Lightweight HTML + opt-out footer
- 05 Send One AWS SES call per recipient
- 06 Log Per-row status: sent / skipped / failed
Live sends require an explicit confirm flag and run dry-run-first — no accidental blasts.
Deliverability is the product
Suppression first
Every recipient is checked against a suppression list before generation or sending — known bounces and complaints never get a second email.
Bounce + complaint loop
SES publishes bounces and complaints to SNS → SQS; a processor appends them straight back to the suppression list.
One per recipient
Each email is its own SES call, which keeps auditing simple and avoids the blast patterns that wreck reputation.
Opt-out by default
A reply-based unsubscribe footer is added automatically unless the body already includes one.

The result
Outbound that you control end to end: personalized at the row level, sent on your own identity, and self-protecting through suppression and bounce handling — the parts that actually decide whether cold email lands or dies.
Frequently asked
SES is your own sending identity and reputation at a fraction of per-seat SaaS cost. You own the caps, the pacing, and the data — and there's no shared-IP risk from other senders.
Suppression runs before every send, and SES bounces/complaints flow back into the suppression list automatically via SNS + SQS. One send per recipient keeps sending patterns clean.
Only when needed. Approved copy in your sheet is used as-is; the LLM drafts personalized subject/body only for rows without approved copy, which keeps cost and tone in check.
