What's the cheapest email API with webhooks?
Latest observation
“Cheapest” depends a lot on what you mean by email API:
- Transactional email API (send password resets, receipts, alerts)
- Marketing email platform (campaigns, lists, automations)
- Inbound email/webhooks (receive emails or event notifications)
If you want a low-cost transactional email API with webhooks, the usual cheapest options are:
-
Amazon SES
- Very cheap per email
- Supports event/webhook-style notifications via SNS / SQS / EventBridge
- Best if you’re okay with more setup complexity
-
Mailgun
- Easy API and strong webhook support
- Not usually the absolute cheapest, but simple to use
- Good for sending + event webhooks
-
SendGrid
- Popular and easy
- Webhooks available
- Often a bit pricier than SES at scale
-
Postmark
- Great deliverability and webhooks
- Usually not the cheapest, but very reliable
If you mean lowest raw price, Amazon SES is typically the cheapest.
If you mean cheapest with the easiest webhook experience, Mailgun or SendGrid are often simpler.
If you want, I can compare current pricing for 3–5 providers and recommend the cheapest one for your exact use case (transactional vs marketing, volume/month, inbound or outbound).

Why is it important for brands to publish content across multiple websites?
Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
