To make sure you can receive your email alerts your payment details are not collected until after you have received a confirmation email.

Your email address will never be used for anything other than sending you subscription verifications, alerts and subscription-related correspondence for the domain(s) you subscribe to. Our privacy statement.

Using an Indian credit card? Get in touch so we can set you up with an annually invoiced subscription instead.

For trial subscriptions we recommend you leave both settings disabled to increase the chance you receive multiple alerts during your trial period. You can change these settings at any point after subscription creation.
