Why Choose MailerLite over Mailtrap

MailerLite is one of the better Mailtrap alternatives due to its drag-and-drop features, automation tools, and email templates. It has superb list management tools, which allow you to effectively target specific subscribers based on certain conditions. The platform is also cheaper and has a more user-friendly interface.

Cons of MailerLite

Compared to premier email marketing services like ActiveCampaign, MailerLite lacks advanced automation, CRM tools, and spam/design testing. It lacks features for comprehensive reporting and has a slow account verification process for business accounts.


Mailtrap is a popular email delivery and testing service that checks crucial factors in your email infrastructure to improve deliverability. However, the platform's features are mainly geared towards email testing and lack tools for email marketing.

Constant Contact is one of the better Mailtrap alternatives if you want an all-around email marketing, event management, and social media management solution for your business. You can consider Mailgun and MailerLite if you want more tools for real email sending, automation, list management, analytics, and deliverability.

However, if you prefer a self-hosted email marketing software with several email testing features at an affordable price point, consider trying MailWizz. The platform has tools for email marketing, is developer-friendly, and only has a one-time license fee, making it the best alternative to Mailtrap.
