While donors can opt out of text messages sent from your organization by replying "stop" (more here), this opt out does not apply to any SMS reminders or receipts associated with an active recurring donation.
This article details how to stop notifications for a recurring donor.
What text notifications do recurring donors receive?
Payment Receipt: This is the message that is sent once the donation has been charged. The email version will be what you write in the Email Receipt for any other donation. The SMS version will look like this:
Upcoming Payment Reminder: This message is sent about 3-4 days before the next donation will be charged. The email version will be what you write in the Email Receipt for any other donation. The SMS version will look like this:
Credit card expires in 30 days: If the credit card's expiration date is approaching, the supporter will be alerted so they can provide a new date or credit card.
Credit card expired: This alerts the donor that their credit card is expired and they will need to update it to continue donating.
IMPORTANT: While donors can opt out of text messages sent from your organization by replying "stop", this will not opt them out of the SMS reminders or receipts associated with an active recurring donation.
Disable Recurring Donation Notifications for a Donor
First, use the left navigation to head to Existing Reporting > Recurring Donations.
Locate the donor using the search filters.
Select Action on the far-right column > $ Manage Payments.
Here is where you can uncheck the SMS boxes so they won't receive those texts moving forward. Click Save to apply the changes.
Note: For compliance reasons, the Email Payment Receipt cannot be disabled.
