I've been using MailerMine while working on projects like PixaView, TrueCart, and a few other development projects, and I've had a really good experience with it so far.
What I like most is the developer-friendly approach. Integrating the API/SDK into a project is straightforward, and features like contact management and importing contacts can easily fit into an existing backend workflow. I especially liked being able to test contact imports programmatically instead of having to manage everything manually.
For projects where I'm building and testing different features, having MailerMine connected to the application makes email and contact-related workflows much easier to manage. The platform feels simple enough to get started with while still giving developers the flexibility they need.
Overall, MailerMine has been a really useful addition to my projects, and I think it's a great option for developers and teams looking for a simple way to handle contacts and email workflows. Definitely worth checking out.
