Lettermint for Agencies

Yes, you can add your clients' domains to your account. After configuring the DNS records, you can send emails directly from their domains. For example, add example.com and send emails from info@example.com.

This depends on your plan. With our Pro plan at €15 per month, you can add unlimited domains and projects. Ideal for agencies sending transactional and marketing emails for multiple clients.

For security, it's smart to create a separate project for each client. You can request an API key per project that only works for domains within that project. This keeps clients separated and prevents emails from being sent from the wrong domain by accident.

Yes, you can invite team members and clients with their own access rights. For example, give a developer access only to the projects they work on.

Yes, in our dashboard you can see all statistics per domain and project. Think of sent, delivered or bounces. You can also retrieve this data via the API or receive it in real-time as a webhook.

Want to charge this to your clients? You can fully automate this via the API. That way, clients only pay for delivered emails.

For WordPress we have an official plugin in the WordPress Plugin Directory. Does your client use a different system? With SMTP you can integrate Lettermint with almost any application. We also offer an API, SDKs for Node.js, PHP and Zapier for no-code integrations.
