A common question when starting a cold email campaign is, “How many emails can I send a day?”

In the first place that will depend on the email service provider you are currently using, as they are the ones who initially set their limits. Nonetheless, these are not the only limits to bear in mind.

Setting limits and avoiding blasts is a major concern as it greatly helps to reduce spam.

In this article, we will be diving into the most popular email service providers, but also discussing the optimal sending limit for our campaign, while taking into account our sender reputation and email deliverability.

We should not forget that cold email is more of a marathon than a sprint.

Slow and steady wins the race.

What are the risks of exceeding limits?

Limits are there for a reason, so before we dive into sending out our email campaigns we need to revise closely how many emails we can actually send out without risking our sender reputation.

To begin with, if we exceed the limit set in place by our provider, we run the risk of being suspended. This could last 24 hours or it could be permanent. Not an ideal situation.

In addition, if we send a large amount of emails and a large percentage bounces back due to an exceeded limit we could face further risks where our brand image and sender reputation can take a serious hit.

How can I respect email-sending limits?

The best way to make sure that your cold email campaign is protected is to prepare a schedule throughout the day. If you choose to do this with a cold email tool, you can adjust your settings so that emails are spread out throughout the day and not sent out in the form of blasts

We recommend sending around 100-150 emails a day, spread out throughout the day so you mimic actual human behavior and protect your email deliverability as much as possible.

For scheduling stick to these tips:

  • Respect the weekends
  • Chose timeframes that suit your target audience’s working hours
  • Stick to a 100-daily email limit

Slow and steady wins the race

Email algorithms are tricky and on a daily basis, we see more spammers and scammers pop up, so protecting recipients has become a major concern for email service providers, which is why it is crucial to be sensible about our email campaigns.

We don’t want to send out 300 emails in one day and get a super low response percentage, because that will seriously harm our domain.

If you want to make sure you’re protecting your email deliverability, you should have a good deliverability checklist to ensure you’re following every step correctly.

Whether you’re losing sleep over exceeding limits or just want to save some time, use a tool such as lemlist, where you can automate all of your cold emails and adjust your own limits and schedules!

What are the limits?

We can take into consideration two different types of limits. The limits imposed by our email service providers, and on the other hand the recommended limit to ensure success.

ESP Limits

Generally, email service providers set limits in order to avoid spammers and scammers.

In most cases, the ESP (Email Service Provider) could flag our account as SPAM and shut it down altogether. Which is obviously far from our goal

Here’s a list of 8 of the most popular email service providers, so you can take into account the limitations of your provider.

Gmail and GoogleWorkspace

Gmail is designed for businesses of all types and sizes, it is a cloud-based email marketing solution that assists with creating custom professional email addresses, sending bulk emails, etc.

Recommended limits

Even if we have the ability to send thousands of emails in a 24-hour span, that may not be such a good idea for our personal interests.

The fact that we can sit around all day and watch TV doesn’t mean that we should, does it?

We recommend warming up your account starting at 10-20 emails per day, and ramping up to 100 emails per day by the fourth week or so.

After your account has been properly warmed up you could send up to 150-200 emails a day.

We do not recommend exceeding this amount too much due to the fact that not all your emails will be answered, opened, or maybe even delivered. Bear in mind that bounced email addresses will surely hurt your send reputation and email deliverability.

You want to take a slow and steady pace which will give you the opportunity to stop, check, and tweak if there are any issues arising along the way. It’s also a good idea to have a good email verification tool set in place to help you avoid this risk.

Key Takeaways

  • Limits are there to protect us
  • Slow and steady wins the race. Set out a schedule before jumping into the cold email pool.
  • Stick to a 100-150 sending limit.
  • Be consistent with your cold email campaigns
  • Don’t neglect your email deliverability and be conscious about it.
  • Understanding the rules and limits put in place by our provider can save us a lot of pain.
