I can tell you that Gmail managed to include your reply in the original thread. Maybe other email clients also managed to do it by Subject matching but that's not the standard. So, https://news-web.php.net/php.internals and https://externals.io didn't. The matching logic for externals.io can be found here and it mostly the same as the other email thread detection implementation: https://github.com/mnapoli/externals/blob/486eb208f36d1c2a46d6691dfe2e2b48cebab7ee/src/EmailSynchronizer.php#L137 Specifically, for linking to the original thread check the "References" header and the "In-Reply-To" header. If you use an email client that let you manually edit the fields, the only thing to do is to find the values to put there. That can be done with the view source link on externals.io and looking up on the "Message-ID" header. I guess you can give it a try and reply to my message here. I would have like to test this now as well but I'm on mobile for the rest of the week and tools for this operation are not that mobile friendly. Regards, Alex
