read receipt not working 3.20
I'm curious if there are certain servers that prevent read-receipt from being generated by user? I just got a response email from client and never received any notification that they read the email I sent...
Servicio de atención al cliente por UserEcho
ive also had trouble testing the private delivery.. not sure if it sends.. didnt send to my test emails reliably..
please advise
thanks for all this does however - great tool !
