For Gmail users, there is a daily limit of 2,000 emails sent in a 24 hour period; and for Outlook users, the limit is 5,000 emails sent in a 24 hour period. Once you hit that limit, you are locked out of Gmail or Outlook until that email count resets. Additionally, all emails sent through Groove Flow also contribute to this number. Reps sending, scheduling, and auto-sending hundreds of emails per day will potentially block them from sending any emails at all. Without any kind of limits around how many flow emails a user can send each day, they can get into trouble when they hit these sending limits sending limit.
With Email Throttle, managers and admins can help their users avoid these issues, by limiting and staggering the volume of emails their users send out through flows!
How to Set an Email Sending Limit
Go to your Users Page in Manage My Org
Select the User/Users you want to set an Email Throttle to
Click on Actions and Scroll down to "Set Email Throttle Max"
User the arrow keys or type in a Email Max you wish to set!
For G-Suite customers, the Email Throttle Max is 1,800 flow emails per day. For Microsoft 365 customers, the Email Throttle Max is 4,500 flow emails per day.
You can display the "Email Throttle" column by going to the Settings Cog at the top right and selecting that option
How Does Email Throttle Work?
When users hit their email throttle limit, the rest of the emails in their Outbox or any others they try to send will be re-scheduled for the next day. The re-scheduled items are prioritized based on the people who are furthest along sequentially in your Flow.
For example: If you have set the User's Email Throttle limit to 300 emails per day, but they have auto-scheduled 450 emails to be sent out in step 2 and step 5 of the flow on Monday at 11:00am. 150 emails will be prioritized to be sent out on Tuesday at 11:00am. The emails in the highest step number will be sent first, so step 5's contacts will receive the email before the contacts in step 2.
If there are steps in multiple flows that are scheduled to send out and at the same sequential step, the higher step number will be considered when prioritizing. If they both have the same step number, the step with the higher day will take priority.
For example: Say we have, Flow A with Step 1 (sends out on Day 1), Step 2 (sends out on Day 2), Step 3 (sends out on Day 3). Then we have Flow B with Step 1 (sends out on Day 1), Step 2 (sends out on Day 3), Step 3 (sends out on Day 5). Flow B's Step 3 will be prioritized because they are both the same step, but Flow B has the higher day (in this case Day 5).
Common Use Cases
Give your team's time back! Email throttle will give your team's time back in the day and make sure they do those followup emails which are necessary for fostering a good relationship with prospects and customers.
Avoid hitting Gmail/Outlook's sending limit. As you already know, a big use case here is to prevent your users from hitting Gmail's 2,000 emails, or Outlook's 5,000 emails a day sending limit. Sometimes when users hit this limit too many times, they can be put on a blocklist and will be unable to send emails.
Stagger your Auto-import. If you have the feature Auto-import set up for a flow, there can be hundreds of contacts uploaded to it per-day. Again, you want to make sure your user's aren't hitting that sending email limit, so email throttle is a great way to avoid this!
Email Throttle FAQs
Without using Email Throttle, users are stopped at 1800 Flow emails per day (Gmail), and 4,500 Flow emails per day (Outlook) right now, so that each user has some room to send emails directly from their inbox.
Set a limit lower than that to further regulate how many Flow emails users are sending on a daily basis.
