Mailgun no longer free 100 validation limit

Hi Eric,

Can you provide a list of active plugins on your website?

if I add a customer note in a woocommerce order, it will generate approximately 10 identical API requests to the same email address. Also if a new order is processed it will also generate several API requests to Mailgun.

I added additional code for post.php and shop_order post type, but was not successful.

	if ( "edit.php" == $pagenow && "shop_order" == $wp->query_vars['post_type'] ) {
				return TRUE;
			}
			
			if ( "post.php" == $pagenow && "shop_order" == $wp->query_vars['post_type'] ) {
				return TRUE;
			}

I have approximately 30 plug ins enabled, many are woocommerce related. I can send via PM the list but if you have any ideas what to check in the meantime please let me know.

update; it appears the following code solves the problem

		if ( "post.php" == $pagenow ) {
				return TRUE;
			}
			if ( "admin-ajax.php" == $pagenow ) {
				return TRUE;
			}

but I am unsure if excluding post.php or admin-ajax.php would prevent the mailgun validator from working elsewhere.

I believe someone else mentioned that is_email() function is called many times in WordPress thus this is the reason for excessive (unnecessary) usage of Mailgun e-mail validation.

The problem is not only WooCommerce. I’ve found that editing/saving/modifying a contact form in Contact Form 7 plug-in also causes dozens of unnecessary Mailgun API calls. I would assume this is the case for other plug-ins that use some sort of is_email() functionality.

Some suggestions;

ignore validating e-mails that belong to the site owner, for example, [email protected]

have option to only validate e-mails that originate from a specific page(s). For example, a contact form.

I’ve been able to eliminate most of unnecessary Mailgun API calls by preventing “admin.php”, “post.php” and “admin-ajax.php” using $pagenow conditions but a better solution could be to only allow the validation to occur on the pages you want.

Thank you for providing this plugin but it can be a problem if no limit is set in the Mailgun account. The result could be a hefty $$$ bill for thousands of repetitive validation requests. Perhaps you can come up with an elegant solution to this problem?

Your could try this to exclude the whole admin area:

if ( is_admin() ) {
    return true;
}

And sorry for the trouble, when I initially developed this plugin the validation service was completely free.

Ok, even with my additional conditions I still see many validations when an WooCommerce customer order is triggered (approx. 50 validations per order). I will try your suggestion to add the “is_admin()” condition to see if this helps eliminate them.
Thank you

Unfortunately, “is_admin()” does not help as there are still many duplicate validations. I believe the bulk of them are coming from WooCommerce “front-end” orders.

In the following link I’ve added transients to the validate_email() function. The validated email and its result would be stored in the database for 1 month.

Let me know if it makes things better.

yes this looks like it will do the job. I will try it out.
Thank you.

Hi Jesin,
First, thank you for you work!

Is this modified function used to validate addresses from plugin settings page?

When I try it, I get API calls incremented in the Mailgun panel every time I validate the same email again and again.

And after several attempts this email is getting validated ??
