We are setting up a HR Campaign and e-mail will be going out to ~50,000 employees.
This will be our first large send and HR is trying to understand how long it will take for the emails to go out to everyone, so they can schedule properly.

I found this article:

https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0787230

"It will send out 100 emails at a time with brief pauses between chunks up to a maximum defined in the glide.smtp.max.per.job property. Once that max is reached, any emails that were claimed but are not sent get "unclaimed" and set back to send-ready. The email sending stops until the next time it is activated by the scheduled job."

is this saying:
100 email 1000 times = 100,000 emails
or
100 email until 1000 are sent = 1,000 emails

How much time would it take to send 50,000 emails from our ServiceNow instance?

Hi Rick,

Check how many SMTP sender job you have and if glide.smtp.one_chunk_per_send is false.
The platform is able to send 1000 mails per job and each job is executed every minute.

Assumptions:

  • property glide.smtp.one_chunk_per_send is not active (default)
  • your instance have 2 smtp jobs (like most instances)
  • you don't have any other mail ready to be sent during the campain (I mean mails triggered by ITSM, CSM or any other product)

It would take approximately 25 minutes to send 50 000 emails.
