Best Way to Send Bulk Emails

[lisa_haworth]

Hello,

We built a custom app to send out email notifications to large groups within our organization and we are using Office 365 (cloud) mail service. We have recently found that the Office 365 cloud service blocked emails from being received from our ServiceNow instance due to high spam count. We are using an Active directory DL (Approx 1200 people in the DL)   as the recipient of the communication instead of a ServiceNow group.

Is there a best practice for sending bulk email  notifications such as these?

Any advice will be appreciated!

No way to bet around the spam filter. (besides sending them 50 at a time every 90 seconds - which i wouldn't know how to do in SN)

Best to get the sender whitelisted by your office365 team.

I don't know the feasibility of this but I know that there is an O365 API for sending mail.

It might be possible to send the messages through an integration to the server, thereby avoiding the mail gateway.

Hi Lisa,

Servicenow can deliver 1000+ notifications on a notification. ServiceNow is capable of this now by splitting the email delivery ( 100 per bulk).

There is no specific limitation on this.

Thanks,
