Why integrate with Mailersend
Common scenarios for SaaS companies building Mailersend integrations for their customers.
Enable white-labeled transactional email for your customers
Let your users connect their own MailerSend accounts so emails (invoices, receipts, alerts) are sent from their domain with their branding — not yours. This improves deliverability and trust without you managing email infrastructure per tenant.
Sync user and role data from MailerSend accounts
Pull team member details and roles from your customers' MailerSend accounts using Truto's Unified User Directory API. This is useful for access control, audit logging, or displaying which team members have email-sending permissions inside your product.
Build a Bring Your Own Email Provider (BYOP) workflow
SaaS platforms offering notification or communication features can let end users pick MailerSend as their email provider. Truto handles the auth and connection lifecycle so your team focuses on the product experience, not OAuth flows and token management.
Power event-driven email and SMS dispatch from your platform
When internal events fire (e.g., payment failed, order shipped), your platform can route them through the customer's MailerSend account to send templated emails or SMS messages. This keeps the customer in control of their messaging while your SaaS orchestrates the logic.
Surface email deliverability insights inside your product
Fetch analytics, message statuses, and suppression lists from MailerSend to build in-app dashboards showing open rates, bounces, and spam complaints — giving your users visibility without leaving your product.
What You Can Build
Ship these features with Truto + Mailersend
Concrete product features your team can ship faster by leveraging Truto’s Mailersend integration instead of building from scratch.
Team member and role directory sync
Use Truto's Unified User Directory API to pull MailerSend users and their roles into your app for permissions management, onboarding flows, or audit trails.
In-app MailerSend template picker
Fetch the customer's MailerSend templates and let them map app events to specific email templates directly within your settings UI — no context switching required.
Embedded email performance dashboard
Query MailerSend analytics and message data to render open rates, click rates, and bounce metrics as a native widget inside your product.
Automated suppression list sync
Periodically pull hard bounces, unsubscribes, and spam complaints from MailerSend into your platform to automatically suppress bad addresses and protect your users' sender reputation.
Webhook auto-registration for real-time email status updates
Programmatically register MailerSend webhooks on behalf of your users so delivery, open, and bounce events flow back into your app in real time — zero manual setup for the end user.
Unified email + SMS notification flow
Leverage MailerSend's dual email and SMS capabilities to let your users configure multi-channel notification sequences triggered by events in your platform.

How It Works
From zero to integrated
Go live with Mailersend in under an hour. No boilerplate, no maintenance burden.
Link your customer’s Mailersend account
Use Truto’s frontend SDK to connect your customer’s Mailersend account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.
We handle authentication
Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.
Call our API, we call Mailersend
Truto’s Proxy API is a 1-to-1 mapping of the Mailersend API. You call us, we call Mailersend, and pass the response back in the same cycle.
Unified response format
Every response follows a single format across all integrations. We translate Mailersend’s pagination into unified cursor-based pagination. Data is always in the result attribute.
FAQs
Common questions about Mailersend on Truto
Authentication, rate limits, data freshness, and everything else you need to know before you integrate.
What authentication method does MailerSend use?
MailerSend uses API token-based authentication. End users generate a token from their MailerSend dashboard and provide it during the connection flow. Truto securely stores and manages these tokens so your team doesn't have to.
Which Truto Unified APIs are available for MailerSend?
MailerSend is currently mapped to Truto's Unified User Directory API, which supports reading Users and Roles from connected accounts. Additional tools and unified API mappings can be built on request based on your use case.
Are there specific tools or proxy endpoints available for MailerSend today?
There are no pre-built tools for MailerSend at this time. Truto builds tools on request — if you need support for templates, message dispatch, analytics, suppressions, or webhooks, the Truto team can scope and deliver these based on your requirements.
Does MailerSend enforce rate limits on its API?
Yes. MailerSend applies rate limits that vary by endpoint and plan tier. Truto handles retry logic and rate-limit awareness so your integration degrades gracefully under load without you writing custom backoff logic.
Can I use Truto's proxy to call MailerSend endpoints not yet covered by a Unified API?
Yes. Truto's proxy pass-through lets you make authenticated requests to any MailerSend API endpoint using the stored credentials, even if a unified model or dedicated tool hasn't been built yet. This gives you immediate access while custom tools are being developed.
How fresh is the user and role data synced via the Unified User Directory API?
Data is fetched in real time from the MailerSend API on each request through Truto. There is no caching layer introducing staleness — what MailerSend returns is what your application receives.
