Is AISend Worth It? Cost by Monthly Volume Against Resend and Amazon SES
Short answer: AISend is worth it if you send transactional email from your own domain, want a Resend-compatible API, and want an AI agent to operate it while a person approves and reviews. On price it wins at about 50,000 emails a month ($14 against Resend Pro at $20), loses to Resend Pro at 100,000 ($63 against $35) and to Amazon SES's per-email rate at every volume. AISend is newer and has no long sending history, and it is a paid service: an account needs an active plan, and a verified domain of your own, before it can send.

Fit by team and situation
| Situation | Fit | Why |
|---|---|---|
| Side project under 3,000 emails a month | Probably not | Resend's free plan covers 3,000 emails a month (100 a day) and AISend has no free plan; its cheapest plan is $14 a month. |
| Startup sending about 50,000 a month | Good on price | AISend Pro is $14 a month for 50,000 emails; Resend Pro is $20 for the same volume. |
| Product team sending about 100,000 a month | Check the numbers | AISend Business is $63 a month; Resend Pro lists $35 for 100,000 emails. |
| Team that wants an agent to send and check mail | The reason to choose it | A hosted MCP server with OAuth sign-in lets ChatGPT, Claude, Cursor or Gemini CLI send from your verified domain; you approve the connection, review sent mail on the Emails page and can revoke the key. |
| Sending above roughly 150,000 a month | Ask first | Scale lists 500,000 emails a month but is capped at 5,000 a day today, which is about 150,000 a month. |
| Outreach to purchased lists, bulk marketing | No | AISend is for transactional and consented mail only. |
Monthly cost by volume
Prices from Resend's pricing documentation and Amazon SES pricing, read on November 13, 2026. The SES column is the outbound rate of $0.10 per 1,000 emails only: it leaves out attachments, dedicated IPs and the dashboard, webhooks and suppression handling you would build or configure yourself.
| Emails per month | AISend | Resend | Amazon SES (sending only) |
|---|---|---|---|
| 3,000 | $14 (Pro; no free plan) | $0 (free plan, 100 a day) | $0.30 |
| 10,000 | $14 (Pro) | $20 (Pro) | $1.00 |
| 50,000 | $14 (Pro) | $20 (Pro) | $5.00 |
| 100,000 | $63 (Business) | $35 (Pro) | $10.00 |
| 500,000 | $149 (Scale, capped at 5,000 a day, about 150,000 a month today) | $350 (Scale) | $50.00 |
What the AISend price includes
- A Resend-compatible REST API and a Node.js SDK: a Resend client usually needs only its base URL and API key changed.
- Sending through AWS SES, with SPF and DKIM records to publish for your domain and automatic suppression of bounced and complained addresses.
- Delivery webhooks signed with HMAC-SHA256, and an email-validation quota (5,000 a month on Pro, 25,000 on Business, 100,000 on Scale).
- The MCP connector: hosted at api.aisend.app/mcp with OAuth sign-in, or local with npx aisend-mcp.
- No per-email overage charges: at the monthly limit sending pauses until you upgrade or the quota resets.
What the price does not buy
- A free plan or free sending. Creating an account is free; sending needs an active paid plan.
- Campaigns, automations or newsletters.
- A long sending history: AISend is newer than the vendors above.
- Any volume you like: every plan has a daily cap (2,500 on Pro, 5,000 on Business and Scale), and new accounts ramp up over their first 14 days.
- Sending to anyone but yourself before you verify a domain of your own.
How to decide
- Estimate your monthly and daily peak volume and find the row above.
- If the row favours another vendor on price and you do not need an agent-operated workflow, use that vendor.
- If you want an agent to send and check mail under your approval, create an account, add and verify your domain, connect your assistant from the MCP page, and subscribe monthly. You can cancel any time.
