# A SendGrid alternative you host yourself

SendGrid is great at one thing: pushing email through an API. But its Marketing Campaigns product is hosted SaaS that prices by contacts, and you don't own any of it. Broadcast is the marketing layer you run on your own server for a one-time license (lists, campaigns, automations, and unsubscribe handling) and it sends through Amazon SES, Postmark, Mailgun, or any SMTP, _including SendGrid's own_.

The short answer

The best SendGrid alternative depends on what you used it for. For **transactional email APIs**, the closest alternatives are **Postmark**, **Amazon SES**, and **Mailgun**. For **SendGrid Marketing Campaigns** (newsletters, contact lists, and automations) **Broadcast** is the self-hosted, one-time-purchase ($250) alternative: you run it on your own server, get unlimited subscribers with no per-contact billing, and send through SES, Postmark, Mailgun, or any SMTP relay. Broadcast is the only one of these you actually own.

## At a Glance

What it is

SendGrid: Sending API + SaaS marketing

Broadcast: Owned marketing platform

Pricing

SendGrid: Monthly, per contact/volume

Broadcast: $250 one-time

Sending

SendGrid: Their infrastructure only

Broadcast: SES, Postmark, Mailgun, SMTP

Data & reputation

SendGrid: Their servers & shared IPs

Broadcast: Your server, your domain

**Straight answer:** Broadcast is not a drop-in replacement for SendGrid's transactional Email API. If your app fires password resets and receipts through SendGrid, a like-for-like swap is Postmark, Amazon SES, or Mailgun. Where Broadcast replaces SendGrid is the _marketing_ side: the newsletters, lists, segments, and automations you'd otherwise run in SendGrid Marketing Campaigns. And because Broadcast brings its own delivery layer, you can keep SendGrid purely as an SMTP relay and still move the platform you own onto your own server. You don't have to choose between them on day one.

| Data ownership / residency | Your server (EU-friendly) | US-based SaaS |
| Setup & maintenance | You self-host | Fully managed |

SendGrid wins on managed transactional infrastructure and raw API depth. Broadcast wins when you want to own the marketing platform, stop paying per contact, and keep your sending provider flexible.

## Who Should Choose What

### Choose Broadcast if you…

- • Used SendGrid mainly for newsletters and marketing campaigns
- • Are tired of contact-based pricing that climbs with your list
- • Want to own your platform and subscriber data on your own server
- • Want to choose (or switch) your sending provider freely
- • Prefer a one-time license to a monthly subscription

### Stay on SendGrid (or SES/Postmark) if you…

- • Need a managed transactional Email API for app-generated mail
- • Don't want to run any server yourself
- • Rely on SendGrid's deliverability tooling and dedicated IPs
- • Send purely transactional volume with no marketing layer

Tip: many teams do both: keep a transactional ESP for app mail, and run Broadcast for the marketing list.

## Frequently Asked Questions

Not a fully free one for real volume. Every option still needs a sending service. Amazon SES is the cheapest at about $0.10 per 1,000 emails. For the marketing side, Listmonk is free open-source software you run yourself, and Broadcast is $250 once with automations and support. Both send through SES, so a list of 20,000 costs a few dollars per send.

For SendGrid Marketing Campaigns (newsletters, lists, segments, automations) yes. For SendGrid's transactional Email API, no; Broadcast is a marketing platform, not a raw sending API. Many teams keep a transactional ESP for app mail and use Broadcast for the marketing list.

Yes. Broadcast works with any SMTP relay, so you can point it at SendGrid's SMTP and keep your existing setup, or switch to Amazon SES, Postmark, or Mailgun whenever you like. The sending provider is your choice, not ours.

Free, fully open-source list managers like Listmonk exist, and Amazon SES is the cheapest raw-sending backend. Broadcast isn't free or open-source: it's a one-time-purchase, source-available platform that adds automations, segmentation, templates, and support on top of whatever ESP you choose. See our [self-hosted email software comparison](https://sendbroadcast.net/self-hosted/email-marketing-software).

Broadcast is $250 once. Your only ongoing cost is the sending provider (Amazon SES is roughly $0.10 per 1,000 emails) plus a small server. Past a few thousand contacts, that's usually far below SendGrid's monthly marketing tiers. Run the numbers on our [savings calculator](https://sendbroadcast.net/calculator).
