Image not showing in iOS and Mac email clients

[ldeschenes]

Potentiel conflict between WordPress Core and Apple mail client.

There has been a problem with iOS ad MAC email clients for the last year or so. The problem appeared with a new realease of Apple email client. As far has I remember the problem started with the release of iOS 15 (more than a year ago) and has not been resolved yet.

Since that time, when sending email with embedded image using any WordPress plugin, the embedded images do not appear anymore in Apple email clients. This is ONLY the case for Apple email. It does work fine in ALL others email clients (Outlook, Gmail, etc…. even Outlook app on iOS is OK). Also it has nothing to do with the way the Privacy settings are set on the iPhone.The images were displayed fine before iOS 15 release.

Just do a research on the support forum for “email image not showing in ios mail” and see for yourself. It is all over the place in plugin forums (Mailpoet, Mailchip, ec.) It looks like every plugin has the problem, so it is not a plugin problem. IT MUST BE A CONFLICT BETWEEN WORDPRESS CORE and APPLE MAIL CLIENT.

Most likely the problem is on Apple side. Many of us have tried contacting Apple support to no success.

Someone in WordPress developper team should be able to reproduce that behavior and SORT IT OUT WITH APPLE SUPPORT as who (Apple or WordPress) has to make a modification.

Thanks in advance!

There are a couple of problems implicit in this report

1. The first one is that you are using a plugin, and this place is for reporting problems with WordPress alone (without plugins). Each plugin has it's own support forum, so you might ask in their place to find an answer (I don't know the plugin, so I cannot help you with their support link)

2. Even if there could be a possibility that the plugin used a broken core functionality, currently (and when the report was made) embeds are not supported by wp_mail. The only way to add embeds is by using PHPMailer directly with the phpmailer_init. In this case, you should have reported this in the ​PHPMailer issues section.

3. Last but not least, it happens that I've been playing around with embeds for WP lately, in this ticket #28059. So I could be testing this problem in Sequoia 15.5 with Mail 16.0 (3826.600.51.1.1) app and here is the result:

It seems it has been fixed at some point in between since this was reported.

So, despite this report is invalid for the first two reasons, after some testing I've found that worksforme so I'm going to close it with the later.
