A monthly subscription allows you to test many addresses many times. But if you have a batch of addresses you want to test just once, a monthly subscription may be overkill.
We think most users will find a subscription useful for more than just that one batch test, but if you are sure you just want a one-time batch test we can do it for you. Rather than have you sign up for a subscription, learn how to use CheckTLS, run your tests, and then cancel your subscription, we can run your batch for you for a penny per target ($1 per hundred addresses, minimum $25).
We invoice via PayPal, where you can pay by credit card without creating a PayPal account.
Send Us your billing information and we will get back to you with how to send us your batch.
