We have "Enable Expire Notification" feature enabled with default settings to send notifications at day "zero" before/after subscription expires. But users keep getting those emails multiple times. According to logs - that email is sent after: 1, 3, 6, 11, 21, 31, 41, 70, 100 and 130 days after subscription expires as a result of 5 attempts to rebill CC. Is anyone having similar issue?
Email will be sent multiple times if you use Reattempt of failure because of how that function works. When aMember try to rebill user and got declined error from payment system, aMember will change expiration date of payment and set it to a date in the future. So this will trigger expiration mail for that payment again. If you have 5 attempts of rebill, email should be sent 5 times for that payment. Check Expiration emails in product settings aMember CP -> manage products -> Edit Product -> Send expire notifications. May be you have additional emails here.
