# Lettermint for Agencies

Your clients trust you to build their websites and applications. Make sure their transactional emails are in good hands too. Lettermint lets you manage unlimited domains from a single account, track delivery per project, and scale without breaking the bank.

## One account for all your clients

Managing emails for multiple clients often means multiple accounts and dashboards. With Lettermint, you create a project for each client with separate domains, analytics and API keys. All under one account.

No more logging into different providers or tracking separate invoices. One place to manage email delivery for every website and application you build. Switch between projects without switching accounts.

- Unlimited domains and projects
- Separate API keys per project
- One monthly invoice for all your clients
- Invite team members with their own access rights

## Easy integration

Every client has a different codebase. A simple WordPress website, a Magento webshop or a custom Laravel application. Lettermint integrates easily with any environment.

Clear documentation and ready-to-use SDKs help you get started quickly. Or use SMTP for a universal solution that works everywhere. See all [integrations](https://lettermint.co/integrations.md).

## High deliverability

Password resets, order confirmations and notifications from your clients need to arrive. Our system ensures emails land in the inbox, not in spam.

Focus on your business, not on email problems.

## Made in Europe

Lettermint operates exclusively within Europe, on its own infrastructure. From our servers to our team, everything is European. Your emails and customer data remain within EU borders at all times. Read more about the [European approach](https://lettermint.co/european-email.md).

- **100% GDPR compliant** - Your data never leaves Europe.

- **European infrastructure** - Built and hosted in Europe.

## Frequently asked questions

### Can I send emails on behalf of my clients?

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.

### How many domains can I add?

This depends on your plan. The Pro plan, from €15 per month, includes unlimited domains and projects. Ideal for agencies sending transactional and marketing emails for multiple clients. See [pricing](https://lettermint.co/pricing.md) for the limits per plan.

### Can I create separate API keys per client?

For security, it's smart to create a separate project for each client. You can create 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.

### Can I give team members or clients access to specific projects?

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.

### Can I see how many emails clients are sending?

Yes, the dashboard shows all statistics per domain and project, such as sent, delivered and bounced. You can also retrieve this data through the API or receive it in real time as webhooks.

Want to charge this to your clients? You can fully automate this through the API, so clients pay for exactly the emails they send.

### Which integrations do you support?

For WordPress there is 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. There is also the REST API, official SDKs for languages such as Node.js, PHP and Python, and Zapier and Make for no-code integrations. See all [integrations](https://lettermint.co/integrations.md).

### Where are my emails and those of my clients stored?

All servers are located in Europe. We don't store data longer than necessary and work fully GDPR compliant. No CLOUD Act risks, and support from your timezone. Read more about the [European approach](https://lettermint.co/european-email.md).

### Can I also send newsletters and marketing emails?

Yes, besides [transactional emails](https://lettermint.co/features/transactional-emails) Lettermint offers [broadcast emails](https://lettermint.co/features/broadcast-emails) for newsletters, campaigns and other marketing emails. All from the same European infrastructure.
