I have updated my wordpress to the new 5.7 version, I have a function in my functions.php file to send an email.

The thing is, i have used this function before and it all worked well. Now after upgrading, i am unable send email from my custom function send_email()

Custom email function in functions.php

 function send_email(){
        $from = Admin [email protected];
        $to = [email protected];
        $subject = Lamza Activation;
        $activationEmail = '';
        $headers = From: . $from . PHP_EOL;
        $headers = array('Content-Type: text/html; charset=UTF-8');
        wp_mail($to, $subject, $activationEmail, $headers);
    }

I keep getting false value.

I am able to send test email using Easy WP SMTP but I can not on my function.

I need to know what I need to change, configurations or is it my human error.

Thanks yall

The way you're applying the headers is incorrect. You set a "from" address in the headers as a string, and then you immediately overwrite that with an array (so the "from" address is lost). (You're also setting the $from address twice)

Try it this way:

function send_email(){
   $to = $email;
   $subject = "Lamza Activation";
   $activationEmail = '';
   $from = "testing <[email protected]>";
   $headers[] = "From:" . $from . PHP_EOL;
   $headers[] = 'Content-Type: text/html; charset=UTF-8';
   wp_mail($to, $subject, $activationEmail, $headers);
}

OR, you could also use the wp_mail filters to set the from address and content type instead.

function send_email(){
   $to = $email;
   $subject = "Lamza Activation";
   $activationEmail = '';
   wp_mail($to, $subject, $activationEmail);
}

add_filter( 'wp_mail_from', function( $from ) {
     return "[email protected]";
});

add_filter( 'wp_mail_from_name', function( $from_name ) {
     return "testing";
});

add_filter( 'wp_mail_content_type', function( $content_type {
     return 'text/html';
});

// This one you may not need as WP defaults to UTF-8...
add_filter( 'wp_mail_charset', function( $charset ) {
     return 'UTF-8';
});
