BT internet email addresses causing hard bounces
There’s been a global issue with BT internet email addresses over the last few days. This means that email sent to those email addresses has been producing a ‘hard bounce’ The problem was first noticed late last week and at present it’s not clear if the problem has been resolved.
Many ESP’s have a threshold on the number of times that an email address can hard bounce before it is put into quarantine. This is to stop problems with you becoming ‘blacklisted’ and therefore not being able to send emails to a specific domain or domains.
Check your email reports for high hard bounce rates and if you can, find out what email addresses are affected. Work with your ESP on the best course of action.
