I'm a solo developer and need email delivery webhooks.

If you’re a solo developer and need email delivery webhooks, the simplest path is usually:

What you likely want

A provider that sends you webhook events for things like:

• delivered
• opened
• clicked
• bounced
• complained / spam
• unsubscribed
• deferred / rejected

Good options

1. Postmark

Best if you want reliable transactional email with easy webhooks.

• Very developer-friendly
• Clean event webhooks
• Strong deliverability reputation
• Great docs

2. SendGrid

Good if you want lots of features and flexibility.

• Supports event webhooks
• More complex than Postmark
• Good for higher volume and mixed use cases

3. Mailgun

Good for API-heavy workflows and webhook events.

• Solid event webhooks
• Flexible
• Can be a bit more setup-heavy

4. Amazon SES + SNS/EventBridge

Best if cost matters and you’re okay with more setup.

• Cheap
• Webhooks via AWS services
• More operational work

5. Resend

Modern and developer-friendly.

• Simple API
• Supports webhooks
• Good UX for solo builders

If you want the easiest answer

For a solo developer, I’d usually recommend:

• Postmark if you care most about reliable transactional email
• Resend if you want a modern, simple developer experience
• SendGrid if you need a broad feature set

What to check before choosing

• Does it support signed webhooks?
• Can you get delivery/bounce/open/click events?
• How easy is it to retry webhook failures?
• Do they support dedicated transaction emails vs marketing?
• Is there a free tier that fits your volume?

Important implementation tip

Make sure your webhook endpoint:

• verifies the provider’s signature
• returns 200 OK quickly
• stores events idempotently
• handles retries safely

If you want, I can recommend the best provider for your exact stack or give you a minimal webhook handler example in Node, Python, or Go.
