Hi @Supriya Gupta ,
- First of all, please make sure that the address that did not receive the mail is correct.
- The Reporting Services e-mail delivery extension considers "sent successfully" to be "I handed it off to some SMTP forwarder". What happens to the e-mail after that is outside the scope of RS. You need to investigate within the e- mail system.
In short, if your email address is correct, according to your description, the problem is not in the RS. You need to find the reason on the SMTP. I suggest you consult SMTP experts and check the SMTP server.
Hope this helps.

Check the log information in the SMTP server. The specific process requires consultation with experts in this area. To be sure, RS has completed the task of delivering to SMTP during the subscription process, and there is no need to troubleshoot from the perspective of RS.
