Elastic Email – Transactional Emails

Hi,

You are using SMTP, so you can put this in your functions.php:

add_filter( 'wp_mail', 'my_wp_mail_filter' );
function my_wp_mail_filter( $args ) {
	
	$args['headers]['IsTransactional'] = 'True';
	
	return $args;
}

I’m not much of a dev person, could you please tell me where functions.php might be located?

Doing a quick search in the PostSMTP plugin directory there’s two file paths with functions.php:

/public_html/wp-content/plugins/post-smtp/Postman/Postman-Mail/google-api-client/vendor/guzzlehttp/psr7/src/functions.php

/public_html/wp-content/plugins/post-smtp/Postman/Postman-Mail/mailgun/vendor/clue/stream-filter/src/functions.php

Or perhaps it’s the functions.php in:

public_html/wp-includes/functions.php

I tried pasting the code snippet on one of the functions.php as a small test, I noticed that on the line

$args['headers]['IsTransactional'] = 'True';

There’s the error: Syntax error, unexpected T_STRING, expecting ']'

Sorry, put in your theme functions.php, end of file

Putting it in the end of my theme’s function.php file lead to a Parse Error page.

It had to do with the error: Syntax error, unexpected T_STRING, expecting ']'

Forgot a semicolon

$args['headers']['IsTransactional'] = 'True';

I put it in and this time no error page, but I’m still seeing the ‘UNSUBSCRIBE’ link on the bottom of my emails that ElasticEmail automatically generates for non-transactional emails.

Checking the Session Transcript in the Email Log for the test email I sent out after inserting the code snippet, I didn’t see anything regarding “transactional” with a quick Ctrl+F search, so I’m guessing it wasn’t inserted?

go to the mail you received and open the source, check for ‘IsTransactional’ string.

After retesting by sending myself another email, I looked at the source and wasn’t able to find ‘IsTransactional’.

Also I realized that this would only be a temporary measure either way since my theme (Avada) isn’t automatically updated since it’s a multi-site. So I would manually replace the theme’s folder whenever a new version of Avada comes out.

I will do my best to do it on my local environment and I will update.

Thank you. Just a note (in case you didn’t know) Elastic Email accounts are free and can send 5K emails for free a day.

I don’t think they have free anymore, but I have an old account so it’s free ??

well, I did a stupid mistake, don’t tell anyone. the right code to put in theme functions.php:

add_filter( 'wp_mail', function($data) {
    $data['headers'][] = 'isTransactional: True';

    return $data;
});

Thank you, now I can see the ‘IsTransactional’ in the source. Sad thing though is that Elastic Email only changed the ‘UNSUBSCRIBE’ string they auto-add on the bottom to ‘MANAGE NOTIFICATIONS’, which is essentially the same thing.

Any way to have this integrated somehow in the plugin or added somewhere else other than the themes’ function.php?
