How long does it take for YAMM to send my emails?

The execution time for your mail merge delivery is mainly impacted by the number of emails to send. This article will provide you an estimation of the sending time speed depending on the number of emails you want to send.

Overview of the execution sending time

Methodology 

For our survey we took a sample of more than 65,000 campaigns that have been sent out with YAMM during two weeks. 

According to our analyses, about 87% of our users send less than 50 emails / 24 hours. This means that to track bigger emailing campaigns (specifically more than 400 emails / 24 hours), we had to take smaller samples of customers, reducing the accuracy of our survey.

Therefore, please bare in mind that all the figures that are exposed 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 campaigns, so all our figures should be treated cautiously.

Summary of the different execution times of your campaigns

As you can see, it should take on average less than 1 minute if you are sending up to 50 emails. Between 50 and 400 emails, YAMM will send your campaigns in less than 10 minutes. This sending time will increase if you are sending even more, up to half an hour if you are sending more than 1,200 emails.

Surprisingly, the size of your draft doesn't impact much on the execution time. Whether your draft weights 1KB or 15MB, the execution time is very much the same. For example, if you are planning to send between 1,200 and 1,500 emails, it will take both +/- 30 minutes to send light emails (5KB) and heavy emails (5MB).

So the important thing that you have to remind when estimating the sending time, is the number of emails you want to send.

Recommendation before sending your mail merge

When you hit the 'Send Emails' button on YAMM interface, a progress bar will be displayed and you will have to leave your spreadsheet open so that the add-on can send all your emails. So if you are planning to send a large number of emails (more than 1,000 for example), we recommend to use our scheduling option to send emails later as you can shut down your computer and YAMM will still continue to send your mail merge.

If you want to send your emails right away (without using the scheduling feature), based on our calculations, if we estimate that it will take more than 10 minutes for your campaign to be delivered, we will display a informative warning about this just after clicking on 'Send Emails':
