A Mailgun alternative with templates and more than email
Mailgun is an email API and SMTP service with a deliverability focus. SenderKit adds dashboard-managed templates and SMS and push on top of a developer-first API, with no provider lock-in. Here's how they compare — and where Mailgun still wins.
Why teams look for a Mailgun alternative
More than email
Mailgun is email-only. SenderKit sends transactional email, SMS, and push through one API, so notifications across channels live in one place.
Templates out of code
Manage and version message templates in a dashboard and change copy without a deploy.
One simple API and free tier
A developer-first API with typed SDKs and a CLI, free up to 3,000 messages a month.
No lock-in
Route through Amazon SES, Postmark, SendGrid, or SMTP and switch delivery without rewriting your send code.

Frequently asked questions
Is SenderKit a good Mailgun alternative for transactional email?
Yes. It covers the same core — a developer API and SMTP-style transactional sending — and adds dashboard template management and SMS/push, without locking you to one delivery provider.
Does SenderKit offer email validation like Mailgun?
No. Email address validation/verification is a separate Mailgun product and isn't part of SenderKit, which focuses on sending and template orchestration.
Can I keep my current deliverability setup?
Yes. Route through Amazon SES, Postmark, SendGrid, or SMTP, so you keep the delivery you trust while gaining templates and multi-channel sending.
How much does SenderKit cost?
Free up to 3,000 messages a month, then simple usage-based pricing. See the pricing page for current tiers.
