Super Email Sender getting stopped after sending 81 emails
I don't understand what is wrong with it. After sending 81 emails the campaigns were getting stopped automatically. There was an error appearing in the sending logs
"True Error Sending Email!4.7.0 Try Again later, closing the connection. (MAIL) w14sm3866071pfn.3 - "
Please check the attachments for the two campaigns that faced the
same problems. Kindly let me know what to do? Thank you
Please help me or advise me.
Waiting for reply
what is the SMPT used here?
