Main Roadmap

Security scanners and bots inflate open/click metrics.Detect likely bot activity and label it, so it can be excluded from engagement metrics. Provide that info in webhooks payload.

Email API/SMTP code samples (credentials) are buried under Domains and hard to find/copy.Surface API/SMTP credentials with clearer navigation.

Update navigation: API/SMTP code samples

Template edits are risky without history and rollback.Introduce versioning with diff/restore and version labels.

Templates: versioning and history

Sandbox users can’t programmatically react to test messages, only to retrieve them via API.Emit webhooks for emails received in sandboxes with email payloads.

Sandbox webhooks

Let subscribers choose what types of emails they receive instead of unsubscribing completely.Create custom preference centers with multiple subscription categories.Reduce total unsubscribes while respecting user preferences and maintaining compliance.

Unsubscribe Groups (category‑based opt‑out)

It’s hard to optimize subject/content without experiments.Support A/B testing in Campaigns with traffic split and winner selection.

Campaigns: A/B testing

Accept and parse incoming emails for your domains, and deliver their content via webhooks.

Inbound email parsing

Designing responsive emails is harder without MJML tooling.Add MJML support in the template editor and API (compile to HTML).

Templates: MJML support

Implement and publish static IP ranges so that customers can allowlist their outbound connections.

Static IPs range for firewall allowlisting

Blocking addresses one by one is inefficient at domain scale.Allow domain‑level suppression (*example.com) in addition to per‑address blocks (user1@example.com, user2@example.com).

Suppressions: blocklist by recipient domain

Email logs are only accessible via UI.Provide API endpoints to search and retrieve email logs.

Planned

API: Email logs

the SMTP client is a disposable yet in the template neither ‘client.dispose()’ or ‘using var client = …’ is used which can cause resource leaks. Developers with little to no knowledge might not know about this so consider updating the C# template to ensure best practices are used.

Current webhook auth relies on query/basic auth which is less secure.Enhance webhook security with passing auth tokens in headers or/and implementing signed requests.

Webhooks: advanced security

I would like to enforce SSO. Currently SSO is accessible via a specific link however users forget and use the standard sign in page which allow them to connect via the normal auth system. When configured SSO, the standard page should detect the domain and enforced the usage of the SSO setup

SSO - when configured, block sign in form that domain

Add a dark theme with a toggle and system preference support.

UI: Dark mode

Control email delivery speed for large campaigns to avoid overwhelming recipient servers and improve deliverability.

Campaigns: Throttling

Setting up Mailtrap with Vercel requires manual env configuration.Add a native Vercel integration to manage project environment variables for Mailtrap.

Vercel integration

I am currently using the plugin Postman SMTP Setup, which also accepts APIs (SendGrid, MailerSend which connect with API) and the plugin team continuously adds new mailers. It would be great if you guys could contact them so they could add you as an option (they have both free and premium plans, but everyone can do a complete setup on the free plan, also they are well-maintained unlike other unsafe free Wordpress SMTP plugins). I prefer connecting through API as it’s a better connection. I know developers use mailtrap a lot, but I think mailtrap is user-friendly enough to also attract more standard wordpress-based webshops with mostly plugins.

Integration: Wordpress
