EmailEngine is an email client but for apps, not people. It connects to the user's email server, translates REST API requests from the app to IMAP and SMTP commands, and sends webhooks for changes like new or deleted emails.

Take control of your email-sending reliability with the SMTP Debug Tool, a professional-grade yet free solution for diagnosing SMTP connection problems. This tool tests your connection with email services such as Amazon SES, SendGrid, and Sendinblue by sending a sample email and recording the entire server communication log. Use this log to investigate and resolve any issues in your SMTP setup. Designed with user safety as a priority, the tool encrypts all connections, does not retain session data, and offers the option to test without credentials using the “SMTP Blackhole” feature. Rest assured your email testing is as secure as it is effective.

  • Show HN: Sunnybox – An Email API for Effortless IMAP Integration
    When I started with https://emailengine.app, a similar product, I also considered releasing it as a SaaS. But looking at the competition, it seemed too complicated for me (just look at the compliance list for Nylas Email API https://www.nylas.com/security/#compliance ). Will be interesting to see how it works out for you. Good luck! - Source: Hacker News / over 1 year ago
  • Mike Perham of Sidekiq: “If you build something valuable, charge money for it.”
    Oh, yeah, I forgot my pitch. The link is https://emailengine.app - EnailEngine acts as a mail client, basically the same way Thunderbird runs on desktop, or the iPhone Mail on phone, but instead of a GUI it has REST API and instead of desktop notifications it sends JSON webhooks. And instead of a single email account, it can manage thousands of accounts. - Source: Hacker News / about 2 years ago

    Well, I for one, hope that email stays as complicated as described in the post. Otherwise my project that simplifies access to email accounts (https://emailengine.app) would get no traction :D. - Source: Hacker News / about 2 years ago
  • Professional / enterprise experience with EmailEngine?
    I'd like to know if anyone here can share some experience using https://emailengine.app in a larger environment, e.g. Managing / watching 100-200 email accounts and processing ~50.000-100.000 mails per day? Source: over 2 years ago
  • Why is the JavaScript ecosystem like this
    I had the same issues when I started with https://emailengine.app - just like Ghost, it’s an app written in Nodejs. I tried multiple distribution options at first and finally went with complete self containment. All modules are pre-installed during the publishing step and thus the user never needs to run npm. Or if you download the “compiled” single binary version you don’t even need node as it’s bundled with the... - Source: Hacker News / over 2 years ago
