The time it takes to deliver your mail merge is mainly affected by the number of emails to send. This article provides an estimation of the time taken, depending on the number of emails you want to send and explains how the timezone affects the time your mail merge start being sent.
Overview of the time taken to deliver your mail merge
Methodology
We surveyed a sample of more than 65,000 mail merges that were sent out with YAMM over two weeks.
According to our analysis, about 87% of our users send fewer than 50 emails / 24 hours. This means that to track bigger emailing mail merges (specifically more than 400 emails / 24 hours), we had to take smaller samples of customers, reducing the accuracy of our survey.
Therefore, bear in mind that all the figures that are presented in this article are only estimations and average data. It may indeed take more (or less!) time for some of you to send all your mail merge, so you should tread all our figures cautiously.
Summary of the different execution times of your mail merges
| Number of emails to send | Average execution time |
| 0 < X ≤ 50 | 37 s |
| 50 < X ≤ 200 | 2 min |
| 200 < X ≤ 400 | 7 min |
| 400 < X ≤ 800 | 12 min |
| 800 < X ≤ 1200 | 21 min |
| 1200 < X ≤ 1500 | 32 min |
As you can see, it takes on average less than a minute to send up to 50 emails. For between 50 and 400 emails, YAMM sends your mail merges in less than 10 minutes. This time it takes to deliver your mail merge increases if you send even more: up to half an hour if you send more than 1,200 emails.
The size of your draft doesn't greatly affect the execution time. Whether your draft is 1 KB or 15 MB, the execution time is much the same. For example, if you are planning to send between 1,200 and 1,500 emails, it will take +/- 30 minutes to send either light emails (5 KB) or heavy emails (5 MB).
The important thing that you have to remember when estimating the time it takes to deliver your mail merge is the number of emails you want to send.
Recommendation before sending your mail merge
When you hit the Send emails button in the YAMM interface, a progress bar is displayed, and you have to leave your spreadsheet open so the add-on can send all your emails. Therefore, if you are planning to send a large number of emails (more than 1,000 for example), we recommend using our scheduling option to send emails later as you can shut down your computer and YAMM continues to send your mail merge.
If you send your mail merge right away (without using the scheduling feature), and the estimated time for your mail merge to be delivered is more than 10 minutes, an information dialog appears just after you click Send emails.
Please note that your timezone configuration can affect the time it takes to deliver your mail merge. Learn more: At what time is your mail merge sent

sending emails slow is actually natural behaviour and a lot better than 400 in 10 minutes. usually this encounters blocks. why not having a throttle feature for 50 emails per hour ?
What I do for this is create a BatchNumber column in my sheet where I group sets of 10 or 20 rows as 1, 2, 3 and filter to the batch number so that only that amount is sent out at a time.
Then I set a calendar reminder for X hours later to send BatchNumber 2.
Even though my account has the capacity to send 400/24hrs, how can I limit it to a smaller number? My campaign has gone into the overlimit issue and now everyday it is only sending a handful.
Also, it would be mighty useful if status of the emails not sent due to limit issue is mentioned as Sending Overlimit, rather than a generic 'Bounce'. I can't even filter the list to create a new campaign for that.
Also, using Outbound Olga's idea of creating batches, can I schedule all the batches so that I dont have to manually trigger each batch?
Hi, Raza Jaffri - BaltoroTech,
Concerning your issue, have a look at the following article "https://support.yet-another-mail-merge.com/hc/en-us/articles/211869705" about Scheduling batch delibery, it also teaches how to leave quota for your campaign !
Do not hesitate to leave us a comment if you encounter any other issues !
Thanks

We want to do mail merge so how can we do it at 4 different times at night?
Hey,
At the moment you can schedule a mail merge for the time you want it, but you can currently schedule 1 mail merge per account.
Schedule batch delivery / send emails later
Let us know if you have any further questions.
Best regards,
