MailerSend Integrations: 33 Native + Zapier + API
MailerSend catalogs 33 native integrations in its official directory, exposes 8,000+ apps through the Zapier connector, and ships 6 first-party SDKs plus a REST API, a Go CLI, and a first-party MCP server. That surface area is unusually developer-forward for an all-in-one ESP, a legacy of the platform spinning off from MailerLite in 2019 as its dedicated transactional sibling, then adding drag-and-drop templates, SMS, DMARC monitoring and MCP over the following six years.
Buyers comparing MailerSend to Postmark, SendGrid or Brevo should know that MailerSend leans hard into automation platforms and modern devtools (Supabase, Firebase, React Email, Laravel driver, Symfony transport) rather than legacy CRM/marketing suites. If your stack is a serverless backend, a Jamstack site or a no-code workflow tool, the connector list below covers most of the wiring you would otherwise write by hand.

Frequently asked questions
Does MailerSend have an official WordPress plugin?
Yes. MailerSend maintains an official WordPress plugin that hooks the core wp_mail function and routes every email through the MailerSend API, so form plugins, WooCommerce and manual admin notifications all inherit deliverability, tracking and template management without extra code. It supports API-token authentication, per-plugin template overrides, and coexists with SMTP plugins if you prefer to keep some traffic on port 587.
How do I connect MailerSend to Zapier?
Install the official MailerSend Zapier connector, authorize it with an API token, and pick from triggers (delivered, opened, clicked, hard bounce, spam complaint) or actions (send email, add recipient to suppression list). Zapier then bridges MailerSend to 8,000+ downstream apps. For higher-volume automations use the Make or Pipedream integrations instead, since Zapier tasks meter every step and can become expensive above a few thousand runs per month.
Is there a WooCommerce integration for MailerSend transactional emails?
Yes. WooCommerce order, refund and shipping emails can be routed through MailerSend two ways: install the official MailerSend WordPress plugin so wp_mail (which WooCommerce uses) hits the API, or configure the WooCommerce SMTP settings to point at smtp.mailersend.net on port 587 with per-user credentials. The plugin path is preferred because it gives you API-level analytics, template overrides and per-message tracking.
Can I use MailerSend with Laravel or Symfony?
Yes. Laravel apps use the official mailersend/mailersend Laravel driver, published on Packagist and maintained by MailerSend, which swaps the default mailer to the MailerSend API and supports queued jobs, template IDs and personalization variables. Symfony apps use the Symfony Mailer component with the MailerSend transport (DSN starts with mailersend+api://) so DI, messenger workers and mailer events all keep working without custom wiring.
How do I trigger MailerSend emails from Supabase or Firebase?
For Supabase, deploy the official Edge Function template that calls the MailerSend API from a Postgres trigger, a webhook or a database function, useful for auth flows and event-driven notifications. For Firebase, install the MailerSend Firebase extension so Firestore writes to a designated collection auto-generate a MailerSend send with template variables mapped from the document payload, no Cloud Function code required.
Which no-code automation platforms support MailerSend natively?
The official directory lists native MailerSend modules for Make, Pabbly Connect, Integrately, Pipedream, Relay.app, Airtable, Airbyte, Zapier and Slack, plus notification-infra platforms like Courier, Knock and Novu. Coverage is broader than most transactional-only ESPs because MailerSend prioritized automation-platform partnerships during 2024-2025 to compete with Postmark and Brevo on time-to-first-email for no-code teams.
