Hello Chad,

Apologies, either I have read your response incorrectly or you have misunderstood my requirement.

It is best practice to sent an HTML email with a plain text attachment. This allows a user to read the information if their client does not support HTML.

Sending either HTML or Plain text is not the issue. I would like to send both to maximise full compatibility.

Apologies, issue appears to have self resolved.

Hello Jason,

My website sends out HTML emails in the following situations:
– new user registers
– user forgets password
– new comment on a users post
– new message received by user front end

My website only sends plains text emails from the contact 7 forms… It therefore IMO made sense to set all emails to be html, and force a specific to be plain text rather than keep default as plain text as default and then specify HTML for a majority.

Does this make sense ?

Hello Shamim, is there a filter/hook I need to use to change this to prevent is being overwritten in updates?

Hello Jason, out of interest i have just sent you a third email. Could you check the header on this for me please ?

Both emails have been sent.

Can you provide me with a direct email address ? That way i can send you the two types of emails directly.

Hello Jason, do you have an email account and i can send you both emails ??

Hello Jason,

Well this is embarrassing. I actually posted the exact same issue in WP-members to try and get a dual approach at this issue as ive been dealing with this for over a week now. I obviously didnt change the beginning of the message.. what an idiot !

——————————————————-

Ok, let me elaborate further. I have enabled DKIM with my hosting provider. I can confirm this is all working ok as if i send an email directly from my mail client ([email protected]) it is signed with DKIM.

However, all emails that are generated via WP-members are not signed with DKIM. I am not sure where to go from here. I have configured Postman to send emails via my mail account ([email protected]) no from what you are saying this should be working ?

Ok, update. Emails appear to be working with DKIM using the SMTP test function. They do not work when being generated from WP-members.

Hello Jason,

Thank you very much !
Turns out i needed to switch from WP SMTP Mail to Postman SMTP.

Issue resolved ??

Whilst i have you here, is there a way to send plain text with the HTML message.

When testing my emails i get the following:

“Message only has text/html MIME parts
You should also include a text version of your message (text/plain)”

Hello Chad,

I have an update, and it is not good.
If i send test emails using WP SMTP mail they are signed with DKIM.
However my registration emails which are sent using WP-members are NOT signed.

I suspect there is an issue between WP-members and WP SMTP mail.
Can you suggest anything or help me add a function to replace SMTP instead ?

Hello Chad, i will go away and talk to my provider and report back. ?? thanks

Hello Jason,

It still does not appear to be working.
All messages are sending as HTML.

To summarize, i have added the below into my functions.php

function set_content_type( $content_type ){
	if($content_type == 'cf7')
		return 'text/plain';
	else
		return 'text/html';
}

//Send HTML emails in WordPress Using wp_mail function
add_filter( 'wp_mail_content_type', 'set_content_type' );

and added “Content-Type: cf7” in the additional headers box for the form.

Any other suggestions ?
