Mobile and Tablet size setting
As part of QA testing, we often need to be able to test specific px widths. e.g. 360px minimum to cover testing on Samsung devices that aren’t the Ultra variants. Being able to set the default mobile and tablet width/length would greatly improve testing functionality.

In-app AI Assistant
A chat interface that has direct access to your account data: sending analytics, campaigns, domains, email logs, and templates. Ask it why your bounce rate spiked last Tuesday, pull up delivery stats by provider, or inspect a specific message — and get answers grounded in your actual numbers, not generic documentation.

Automated Domain Reputation Monitoring
For high-volume senders, reputation issues are often invisible until it's too late — engagement crashes, messages get blocked, and revenue takes a hit. We want to change that by bringing domain reputation monitoring directly into Mailtrap, so you can catch and act on problems before ISPs do. Why it matters You only find out you're in trouble when it's already affecting delivery Proactive monitoring lets you throttle or warm domains before things escalate Blocked transactional or promotional emails = real revenue loss What we're planning Internal sending stats analysis Per ISP deliverability analysis Bounce category analysis Blacklist monitoring Google Postmaster Tools integration A reputation dashboard in a user panel Automated email alerts Webhooks enabling piping signals into own monitoring or incident management tools We'll share updates as we move through each phase. In the meantime — would any of these signals be especially useful for your use case? Let us know in the comments!

MCP server access to HTML Check report from sandbox
Website allows me to open my sandbox, select a message, open HTML Check report. MCP server doesn’t seem to offer the same information. Also would be nice if I could fetch screenshot for each type of device. I want my agent to look up the message that his testing environment just sent and validate that it has no issues and looks good.

Build A Mailtrap Application For PC and Mobile
I just started using mailtrap and it’s has helped me with some of my recent projects, I created an account on mailtrap to see anyone's notification of who signs up or requests in my upcoming site and with the test it's a massive progress, I was able to see any user account name and email with their request I signed up with. but thing is I don’t want to be checking the browser 24/7 to check notification on mailtrap. If it were an application I’ll just receive the notification on my phone which is way better in my opinion. Either ways it’s not a must if its not on your radar, it’s just going to be an improvement which will be a massive win on both our end. Thanks for reading!

Integration tests should not reuse event_id across types
All of the sample payloads use the same event IDs, so you can’t test different types if your service is aware of duplicate event IDs. It’d be nice if they were randomized when you switched tabs altogether so you can also test multiple events of each type.

WordPress RSS post
In Brevo, I can ask the service to automatically generate a newsletter from the last WordPress post(s). It is a kind of automation that creates a message using a given template that has support for getting the RSS fields, subject, date, excerpt, etc,... I have been using this in Brevo for a decade, and in Mailchimp as well. Every week, I get my newsletter sent with my blog's latest updates. That could maybe also used for other kind of RSS files as well.

Email to List
The possibility to create an email address linked to a template and to a list, and when you send to that email, the message is sent to the list with that template. Mailjet has a similar feature. As an independent software developer, I like to automate and get things done as quickly as possible. The possibility, for example, of sending an update notification to a group of customers with my regular mail reader is a plus. Mailtrap would apply the template to my message and deliver it on my behalf.

Display contact list ID in list
My external project uses the API to post a contact to a give contact list however the API only accepts contact list IDs. The ID is not shown anywhere in the contact list. I can only find it by decoding the URL parameters in the list link. Recommendation Display contact list ID directly in the list view Allow the API to search for a particular list by name As it sits now I have to either decode the ID in the link or search through all contact lists, which may be problematic as campaigns grow.

OpenTofu support and Go SDK
Having an official Terraform/OpenTofu provider for Mailtrap to manage resources in a consistent, repeatable way using IaC. Given OpenTofu’s role as the open-source alternative to Terraform, compatibility with it would be important for long-term adoption. An official Go SDK covering the Email API, SMTP, and Sandbox would not only improve the developer experience for Go users but would also serve as a strong foundation for building and maintaining an IaC provider.
