Separate email activity

Now, you can separate email activity by project, app, client, or team. This allows you to:

• Separate sending data and statistics.
• Avoid mistakes like sending emails to users of a different app or project.
• Monitor issues in one sub-account without noise from others.
• Test emails in isolated environments.

Specific user permissions

Each sub-account can have its own set of users with specific permissions. That means:

• Developers can work on their project without access to other sending projects.
• Clients or external contractors can access only selected resources.
• Organization Admins can access and manage all sub-accounts.

Tip: You can find the description of account-level roles in our dedicated article. 

Better organization and management

When you’re managing multiple apps or clients, sub-accounts help keep things tidy since:

• Each sub-account has its own credentials, API keys, and configurations.
• Logs, analytics, and deliverability metrics are scoped to just that sub-account.
• It’s easier to debug and optimize performance per use case.

How the feature works

Let’s say you run a SaaS company with 3 apps and want to create sub-accounts for each tenant in order to give them a secure, isolated, email-sending environment under one system. 

In that case, you could create 3 sub-accounts under your Organization, each with its own SMTP credentials, logs, and settings. Your dev team can work on App A without affecting App B, while your ops team can monitor deliverability separately for each app.

Trigger real emails with simple prompts from AI assistants

You can use Mailtrap MCP to send emails (plain-text, HTML, or both) from AI assistants such as Claude Desktop.

How else can I use the Mailtrap MCP server?

With the Mailtrap MCP server and AI, you can also:

• Generate a report based on data in a database with a ChatBot and and forward it to your team member(s) by leveraging Mailtrap MCP
• Summarize an email, PDF, or any other document with AI (or chat with PDF AI to extract answers in seconds), send it to someone via Mailtrap MCP

For an even more advanced functionality, you can combine Mailtrap MCP with other MCP servers.

The possibilities are endless, so feel free to experiment.

Create fields 

Configure fields before uploading your contacts so you can map them easily afterward. Create custom fields manually and use them to send personalized campaigns. 

Upload contacts

To upload your contacts, all you need is a CSV file populated with your recipients’ data. Easily import it to Mailtrap. Then, map the contact fields such as email, first name, city, etc. 

You can update your contacts, add or remove them from lists, or delete/unsubscribe them. 

Arrange contacts into lists 

Once the contacts are uploaded, group them into lists based on their interests, demographics, behavior, or other segmentation criteria. 

For example, create lists such as ‘dog owners,’ ‘cat owners,’ or ‘parrot owners.’ Add one recipient to multiple lists if needed.  

Send targeted campaigns

Create targeted campaigns that make a difference. Include or exclude specific recipients or lists. Additionally, you can always integrate an AI-powered call center platform to extend these targeted campaigns with automated voice outreach and follow-ups.

Say you want to send a promotional campaign to dog owners only. For that, you just need to include the ‘dog owners’ list and exclude the ‘cat owners’ list. Then, send a campaign right away or schedule it for later.

Drag-and-drop email builder 

Previously, you could only build/edit email templates with an HTML code editor.  

Now, we also have a drag-and-drop email builder that doesn’t require any coding. You can easily build your designs from scratch or choose the desired template from our library. 

The drag-and-drop editor comes with AI-powered Smart Headings, Smart Text, Smart Buttons, and Magic Image, as well as versatile options for building responsive designs. 

Similar to HTML code editor, drag-and-drop editor supports variables, enabling you to personalize your emails whether you’re sending transactional, bulk, or marketing emails. 

Easier integration 

We’ve also introduced several improvements to simplify the integration of Email Templates with Email API/SMTP and Email Testing. 

When you create a template, you can go to the Integration tab and switch between products from there. You’ll see all the necessary credentials within one tab. 

This means that you can easily test the template in staging with Email Testing and, once it’s refined, send it on production using Email API/SMTP. 

Learn more about email templates and their integration here. 

Testing template variables

When you trap your templates in the Email Testing sandbox, you have the option to view and validate all the template variables. This information is available in the Tech info tab. 

You’ll also find the template name with a link to easily access and modify the template if needed. 

Testing and sending templates with API 

Now all our APIs, Email Sending API, Bulk Sending API, and Email Testing API support templates. 

You can use them with any programming language that supports HTTP requests. The detailed RESTful API docs are available here. 

Updated templates are available for all our users.
