Amazon SES alternative for AI agents: AgentiSend compared (2026)
Is AgentiSend an Amazon SES alternative?
Yes, when you would otherwise build the log, the webhooks and the per-key budget yourself. No, when price per message is the deciding number. A Free plan that does not expire: 1,000 emails a month, 100 a day, 3 domains, no card. Then plans from $9 a month (Starter, 30,000 emails). No plan daily cap; delivery paced per inbox provider. Or 20% off paid yearly.
Pick Amazon SES when price per message is the deciding number, when you want a one-call account pause that is already documented, or when you need inbound mail; pick AgentiSend when you want the log, the per-key budget and the kill switch without assembling them. The figures below are from AWS pages fetched on 28 September 2026 and from this product's pricing table and published API.
| What matters | AgentiSend | Amazon SES |
|---|---|---|
| A spending limit per key | Every key is created with a send budget. The send path refuses with agent_budget_exceeded when it is spent, and a key cannot raise its own. The plan inclusion is a second ceiling (plan_limit_reached). | A per-credential send budget is not on the pricing page or the account-sending page. |
| What a refusal tells you | Every refused request carries code, message, fix (the call that repairs it), docs_url and retryable. | PutAccountSendingAttributes documents BadRequestException and TooManyRequestsException. A fix field naming the next call is not on that page. |
| A retry never sends twice | Idempotency-Key is accepted on every endpoint that changes something and remembered for 7 days. | The SendEmail reference does not document an idempotency key. A retried call is not described as returning the first result. |
| How long the log keeps a message | 7 days on Free, 30 on Starter, 90 on Pro, 180 on Scale. It is part of the plan and there is no add-on to buy. | The pricing page does not include a message log. It prices storage you configure yourself, including S3 and CloudWatch. |
