Gmail API support in EmailEngine

From the beginning, EmailEngine has supported only IMAP and SMTP accounts as email backends. This approach has generally been quite effective, as it encompasses the majority of email accounts. Both Gmail and Outlook support IMAP and SMTP with OAuth2, allowing EmailEngine to function even when these platforms disable "non-modern&

Performance tuning

When you start using EmailEngine and have only a few email accounts to test on, you can probably get away with even a very modest server without changing any configuration options. Once your EmailEngine usage grows, this might not be enough anymore. A lot depends on your specific use case.

EmailEngine, an alternative for Nylas Email API

From time to time, people who are looking for alternatives to their current email API vendor, usually Nylas, ask if EmailEngine could be a replacement. Both provide easier access to email accounts via an API. Is EmailEngine cheaper, maybe a more limited version of Nylas?

Sending multiple emails in the same thread

Sometimes you might want to send emails that should end up in the same email thread, for example, follow-up emails. Surprisingly, there is (almost) no server-side threading support. Instead, everything related to threads is handled on the client side. In this case, we would have to compose our emails in

How I turned my open-source project into a business

When I started writing and publishing open-source software about 15 years ago, I was pretty radical about it. I only used permissive licenses like MIT or BSD, as all I cared about was reach. Using a copyleft license with strings attached seemed to hinder that reach. Getting another A-category company

Proxying OAuth2 IMAP connections for Outlook and Gmail

All larger email providers are slowly but steadily moving away from regular password-based authentication for email protocols like IMAP and SMTP. There are multiple options to do so. For example, iCloud requires you to generate application passwords for IMAP. Gmail is pushing OAuth2, even though it also allows application passwords.

Mail merge with EmailEngine

While EmailEngine makes it easy to send regular email through the user's SMTP server with REST API calls, it is also possible to use mail merge. To use it, you need to drop all the regular To/Cc/Bcc addresses from the API request and replace them with

Enabling secrets encryption

By default EmailEngine stores all data in cleartext which is fine for testing but maybe not so much for production. This is why EmailEngine offers a field level encryption option that encrypts all sensitive fields like account passwords, access and refresh tokens.

Improved ChatGPT integration with EmailEngine

EmailEngine, a serious tool from the get-go, had an unexpected twist. As a playful experiment, I integrated it with ChatGPT AI. Surprisingly, over time, this integration turned out to be more than just a joke; it became a valuable feature. Once the ChatGPT integration is activated in EmailEngine, it processes

Shared MS365 mailboxes with EmailEngine

EmailEngine is capable of using MS365 shared mailboxes via OAuth2. This involves adding the shared mailbox to EmailEngine, while the OAuth2 authentication process is handled by a user who already has access to the mentioned mailbox. However, there is a disadvantage to this. At present, EmailEngine anticipates that each OAuth2

Integrating email with a CRM

When integrating email with a CRM system, it typically involves connecting the CRM users' email accounts to the platform. This integration

IMAP

Threading with EmailEngine

In a previous blog post, we discussed how email threads are typically managed on the client side, as virtual entities. Previous attempts to define server-side threading, such as the RFC5256 standard, were mainly useful for mailing-list type threads, assuming that all related emails were located in the same folder. This

Special use mailbox folders

A common area of confusion in IMAP involves mailbox folders, such as the requirements and standards for them. In this post, I aim to provide some clarity on this topic. Although many of us are familiar with a standard set of folders like Inbox, Sent Mail, Drafts, etc., only one

IDs explained

If you have used EmailEngine for a while, you probably notice the abundance of different message identifiers. There's id, emailId, uid, messageId , and under the hood also a sequence identifier that all seemingly do the same thing – identify an email on an IMAP account. What gives, why so
