Dear Anekant Jain,
Good day!!
I understand your concern and since the emails are send with the help of custom Power Automate flow, I would like to suggest you post your concern in the Microsoft Power Automate Community - Power Platform Community so that the related exports will check whether there is any issue with Power Automate flow.
If there is no problem with the Power Automate flow but emails are delayed in delivering, then I believe the problem could be related to Exchange Onlinr Server and I would like request you to post your concern in the Outlook category in this Microsoft Community to get the help Exchange Online/Outlook experts.
Apologies for redirecting you to different community as the members in the category posted focus on the users with the concerns on SharePoint Online and have limited knowledge on the Power Automate & Outlook/Exchange Online, so to get the fast and better assistance, we have redirected you in the correct path.
Appreciate your patience and understanding. Have a great day!!
Best Regards,
Sophia
