Should You Gradually Increase Sending Volume When Sending Cold Emails?

Updated May 2024

Yes, you should gradually increase your sending volume when sending cold emails from a new email address.

I recommend that you only send 40 cold emails per day per email address. However, if you create a brand new email address, you should not immediately send 40 emails per day, as you risk going to spam.

In this article, I will show you how to gradually increase your sending volume so that your cold emails land in the primary inbox (not spam):

Why do email service providers not like sudden increases in sending volume?

Email service providers, such as Gmail and Outlook, will mark your emails as spam if they see a sudden increase in sending volume.

For example, if you buy a new domain, and then create an email address to send cold emails with, then it will be a red flag for email service providers if this brand new email address suddenly starts sending lots of emails from day one.

This is not normal behaviour for a new email account.

Email service providers will assume that your domain and email account are purposely set up to send spam emails, and they will then blacklist all of your emails.

This is why it’s important to gradually build up your sending volume, so that email service providers don’t mark your emails as spam.

Google (Gmail) even states publicly that you should increase sending volume slowly.

How much can you increase your sending volume each week?

I recommend that you follow the below sending volume schedule when sending cold emails from a brand new email address:

Week 1: 5 emails per day per email address.

Week 2: 10 emails per day per email address.

Week 3: 15 emails per day per email address.

Week 4: 20 emails per day per email address.

Week 5: 25 emails per day per email address.

Week 6: 30 emails per day per email address.

Week 7: 35 emails per day per email address.

Week 8: 40 emails per day per email address.

Once you reach 40 cold emails per day per email address, you should not increase further, as you will then risk going to spam.

If you gradually build up your sending volume as described above, then your emails are much less likely to go to spam.

How to send cold email campaigns that gradually increase sending volume

I recommend that you use Emailchaser to send your cold emails because it automatically increases your sending volume in the manner described above, without you needing to do anything.

If you manually send your cold emails from your Gmail or Outlook account, then you will have a hard time tracking how many emails to send each day.

If you send your cold emails with Emailchaser, then you can connect your Gmail or Outlook account, and then upload your leads, and let Emailchaser send your cold emails without you needing to manually click send for each email.

Frequently asked questions

What happens if you don’t gradually build up your sending volume?

If you send lots of cold emails immediately without first building up your sending volume, then your emails are much more likely to go to spam.

How fast should you build up your sending volume?

I recommend that you increase your volume by 5 emails per day each week. You can send 5 emails each day during week 1, and then 40 emails per day per email address by week 8.
