Hi,

Both the mails are getting generated at the same time itself.

Hi Yousaf,

Yes suddenly it is triggering 2 mails no business rule is used to send notification

Double check and make sure you don't have copied notifications or using the same template or anything.
Also check for business rules that cause an update STRAIGHT AFTER an update (or insert).

Because this is set to work on insert or update, there's two possible triggers.  And therefore at least the chance that two transactions happened so quickly it only looks like "exact same time" to a human.
