There is no up-front cost to turn on the Account Updater feature. Once you opt-in, Spreedly will submit all of the cards in your Spreedly vault for updating twice monthly, on the 1st and 15th of every month. You can also opt in on a card level.
The cost of Account Updater can be seen on the pricing page in the Add-on section. Spreedly only charges per card updated or flagged as a result of the Account Updater service. Any charges for Account Updater will appear on your next plan renewal or subscription upgrade, whichever comes first. If you exceed your plan usage levels before your renewal date, any pending Account Updater fees will be added to the total cost of your upgrade.
