DO NOT BUY! - Stay Away.

They do not reply to your support tickets either in a timely manner if at all.

I've had an issue with the plugin giving me an error for the past week, I submitted a ticket and they have ignored my request for help. As my company is reliant on email reminders being sent out from WHMCS via MailerSend it has been losing customers due to terminations all because customers are not being informed about their unpaid invoices.

Their website clearly states Monday - Friday: 01:00 pm - 09:00 pm.
