You have a quota for the amount of emails you can send using mail merge during a rolling 24-hour period. Your quota is based off of your plan type in Streak and Google’s daily sending limits in Gmail.
Additionally, Streak Mail Merge quotas and Gmail sending limits operate independently. For example, while Streak enforces its quota within the application, Gmail's limits encompass all emails sent using your Gmail account, which can include Streak Mail Merge emails or any other emails sent from Gmail directly.
Mail merge sending limits
Pro plan: 1,500 emails per day*
Pro+ plan: 1,500 emails per day*
Enterprise plan: 1,500 emails per day*
*This limit applies to Google Workspace accounts. If you're using a Gmail.com account (i.e. johndoe@gmail.com), you'll be limited to 400 sent emails per day due to a lower limit imposed by Google on these types of accounts.
Checking your quota
Check your real-time quota availability and see how your mail merges have affected your quota in Streak.
To find your currently available quota:
Open the Mail Merges page in the left-hand Streak menu
Click the graph icon at the top right of the page
Understanding the quota chart
Your currently available quota is stated at the top of the chart in green. This is how many emails you can still send within this rolling 24-hour period
The yellow dotted line at the top of the chart shows your quota limit.
The y axis shows your available quota by number of emails you have available to send.
The x axis shows you the past 24 and next 24 hours. The current time (rounded to the nearest hour) will always be at the middle of the x axis.
The mail merge icon shows you when mail merges were sent, which corresponds with a decrease in your available quota over the 24-hour period. You’ll also see how many messages you have scheduled to send over the next 24 hours so you can plan accordingly.
What counts towards the 24-hour limit?
You can view everything affecting your 24-hour quota below the quota graph. This includes messages that were sent with mail merge in the last 24 hours.
Keep in mind that this only includes Streak Mail Merge activity. It does not track other emails sent from your Gmail account outside of Streak.
Streak also takes into account any mail merges you have sent in the next 24 hours so you can plan accordingly. You’ll see these noted on the quote graph and will get a notification if you’re scheduling a mail merge or follow-up that will exceed your quota.
How Gmail and Streak Quotas Interact
Understanding the interaction between Gmail and Streak Mail Merge quotas is important:
Sending emails from Gmail directly reduces your Gmail quota but has no impact on Streak's Mail Merge quota.
For instance, with a Gmail sending limit of 400 emails per day, sending 50 emails manually leaves 350 for other activities. Streak Mail Merge, however, will still display 400 until the quotas overlap, which may lead to Gmail blocking emails beyond its limit.
Such scenarios can result in email delivery failures if Gmail's limit is breached, necessitating close monitoring of Gmail's separate quota.
Practical Tips for Managing Quotas
Regularly check Gmail's usage to prevent unexpected limitations.
Plan campaigns to synchronize Streak Mail Merge and Gmail limits effectively.
Spread out emails across multiple days for larger campaigns to remain within both quotas. Following these methods can help optimize email efficiency and avoid service interruptions.
