AcyMailing vs Mailtrap
A side-by-side editorial comparison of AcyMailing and Mailtrap — release velocity, themes, recent moves, and the top alternatives to consider.
AcyMailing vs Mailtrap: at a glance
What is AcyMailing?
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
Patch releases arriving every few days since the 11.0.0 major. The 11.0.x line is dominated by fixes to what the rewrite disturbed — automation conditions, campaign send settings, custom field handling, add-on integrations — with small improvements alongside, such as REST API errors when a campaign targets disallowed lists and faster module insertion in emails.
What is Mailtrap?
Mailtrap is assembling a full email operations platform, one category step at a time
Mailtrap has moved well past email testing. In three months it added inbound receiving, shipped a free open-source local sandbox, and launched Automated Domain Reputation Monitoring, which pulls sending performance, bounce categories and Google Postmaster data into one dashboard. Between those, the work is compliance and onboarding: per-domain tracking opt-outs for regimes such as CNIL, a Sending Setup page, and an in-app notification centre.

AcyMailing
5.0MKT AUTO
AcyMailing spent 11.0 on a security rewrite and is now paying down the regressions.
◆ Current state
Patch releases arriving every few days since the 11.0.0 major. The 11.0.x line is dominated by fixes to what the rewrite disturbed — automation conditions, campaign send settings, custom field handling, add-on integrations — with small improvements alongside, such as REST API errors when a campaign targets disallowed lists and faster module insertion in emails.
◆ Where it's heading
The arc is consolidation, not expansion. 11.0.0 reworked the codebase for security and added GDPR-aware pixel tracking; 10.11.1 before it patched a SQL injection. Since then the work has been stabilizing that base, and the attachment fix in 11.0.3 even asks administrators to re-upload files or correct permissions.
◆ Prediction
Expect continued 11.0.x patches closing regressions from the rewrite before any new feature work resumes.

Mailtrap is assembling a full email operations platform, one category step at a time
◆ Current state
Mailtrap has moved well past email testing. In three months it added inbound receiving, shipped a free open-source local sandbox, and launched Automated Domain Reputation Monitoring, which pulls sending performance, bounce categories and Google Postmaster data into one dashboard. Between those, the work is compliance and onboarding: per-domain tracking opt-outs for regimes such as CNIL, a Sending Setup page, and an in-app notification centre.
◆ Where it's heading
Each of the last three months has added a capability that sits in a different product category from testing — receiving, local development, deliverability monitoring — which reads as a deliberate widening of the surface rather than opportunistic feature work. The compliance and setup releases in between suggest the same platform being made safe and easy to adopt at the same rate it grows. The Sending Setup page generating a prompt for an AI coding agent is a small signal of where onboarding is expected to happen next.
◆ Prediction
Custom receiving domains were flagged as coming for Inbound, and the reputation dashboard's signal set looks likely to expand; expect one of those to land next rather than a fourth new category.
