If you’ve ever engaged in email automation as a sales or marketing rep, you know that even with the perfect setup, it’s still possible to have your emails fall into the spam folder or simply go undelivered.

This is where email warmup comes in!

Think of all the PE classes you had in school. Your body needed to warm up before engaging in physical activity, right?

Well, email campaigns -sort of, work the same way. You need slowly and gradually build up your email reputation so that it reaches a point where you can send out large amounts of cold B2B emails without getting them flagged as spam.

You generally do this with the help of tools designed for this specific purpose. Or if you use an all-in-one sales automation tool like LaGrowthMachine, you know that it comes with its own email warmup features to make your life easier.

But what exactly is email warmup? Why do you need it? How can you do it effectively? And what are some of the best tools and techniques to get the most out of your warmup?

In this article, we’ll dive into the world of email warmup and provide some proven tips and techniques to help you get the most from your campaigns.

What is email warmup?

At its core, email warmup is the process of building your sender reputation over time. This means gradually sending out emails to build trust with Internet Service Providers (ISPs) and Email Services Providers (ESPs) such as Gmail or Outlook.

Throughout this article, we’ll be using ISPs and ESPs interchangeably as in this context, they both refer to the same thing: a major email provider or email service.

Generally, sales automation tools such as our own LaGrowthMachine include features that allow you to do email warmup without needing any extra tools or manual effort.

You simply need to follow the limits set by our outreach experts and you should be good to go! We even have preset limits on all our channels: LinkedIn, Email, and Twitter!

Why do you need to warm up your email account or IP address?

You might think to yourself, “Why should I bother with warmup when I can just start sending out emails?” It would make sense to think that since you can just fire up a new email account and start sending out prospecting emails to your list of leads.

But here’s the thing: ISPs don’t like it when you suddenly start sending out large amounts of emails right away.

They can easily detect whether you’re a new sender or an established one, and they will usually put your emails in the spam folder. A lot of marketers make the mistake of skipping email warmup altogether and end up dealing with deliverability issues.

Warming up your email account helps you establish -and/or restore, your reputation as a trustworthy sender and increases the chances of your emails being delivered to your intended recipients.

This is especially important when sending out large amounts of automated emails, as ISPs are likely to flag them as spam if they come from an unknown sender.

But that’s far from the only benefit. Email warmup can also help you:

  • Increase your sender reputation: The most obvious and primary use of email warmup is that it helps you establish a good sender reputation with ESPs.
  • Increase the deliverability of your Sales Outreach: Having a warmed-up email account will give an explicit indication that you are a legitimate sender to ESPs, enabling your emails to reach more of your intended recipients, thus increasing your email lead generation..
  • Avoid blacklisting: When you send hundreds of emails left and right, you might get flagged as a spammer and blacklisted by some ESPs. Warming up your email campaigns will help you avoid such unfortunate scenarios.
  • Have better engagement: Better email deliverability means more people will actually receive your emails and be able to engage with them. Think about it, the more emails land in your leads’ inboxes, the better your email open rate, and the better engagement you’ll get!
  • Lower your costs: If your emails end up in the spam folder, you’re literally throwing your money down the drain. By warming up your account and improving your deliverability, you can ensure that your emails are actually reaching their intended audience.

Ultimately, email warmup is a critical step in any email marketing or sales campaign and should not be overlooked.

Next on, we’ll show you how to warm up your email accounts without any additional investment. Spoiler alert, we’re using LaGrowthMachine!😉

How do you warm up an email account?

We’ve defined what email warmup is, we demonstrated why it’s important, and we’ve taken a look at some of the tools that are available to warm up your accounts.

Now let’s get to the nitty-gritty and look at how you can actually go about warming up your account without using a specialized tool.

We’ll be using LaGrowthMachine outbound lead generation campaign example as a use case, and will go into detail about what you need to do in order to properly warm up your account.

Step 1: Create a LaGrowthMachine account and connect it to your channels

Completely free for the first 14 days, LaGrowthMachine is a multichannel sales automation tool designed to help you reach out to your prospects and quickly grow your business.

Creating an account is easy, simple, and with zero commitment. Just a few clicks and you’re already done!

Simply head over to our signup page and fill in the required details and that’s it! All that’s left to do is for you to connect your various channels; LinkedIn, Twitter, and Gmail, to start automation campaigns. 🚀

Step 3: Build your first campaign & warm up your account

We’re finally here! This is where the actual email warmup lies.

Before you go full-throttle mode with your campaigns, it’s important to start your account warmup slowly. And you can do just that with LaGrowthMachine!

We suggest that you start with a small number of emails; say 50 – 100 messages in the first couple of days.

Thanks to our Analytics & Reporting interface, you’ll easily be able to measure the deliverability rates of your campaigns and adjust them accordingly as you go.

Take this example sequence as an example:

Here’s the analytics board related to this campaign:

Insights & Analytics

Once you make sure your emails are being sent to your lead’s inbox and not the spam folder, you can increase your daily send limit.

When using LaGrowthMachine, you can effortlessly change your sending limits by adjusting the slider on your Identity tab.

Our outreach experts recommend you don’t go over 300 messages per day.

300/day is already a lot and if you need to go above that, you should maybe review your targeting and segmentation.

Campaigns with huge amounts of leads generally have lower reply and engagement rates. Here’s a complete guide and analysis of good segmentation practices for you to read through in order to understand our perspective on this specific issue!

Step 4: Enrich your leads’ data and launch your campaign 📧

Once you’ve completed the warmup phase and you feel your account is ready, it’s time to launch your first campaign!

To complete the process, choose one of our many templates and customize it to match your outreach objective:

  • We always recommend going for a multichannel campaign, using at least LinkedIn and Emails if you’re working in B2B. This will help you generate up to 3.5x more leads.
  • Once your workflow is ready and your contacts are uploaded, all that remains is to take care of your email copywriting or otherwise.
  • Your lead’s data will be enriched automatically as soon as you launch your campaign.
  • And that’s it, you’ve now started your own first (- hopefully multichannel) campaign!

All that’s left to do is to monitor your analytics dashboard and track the performance of your campaign. 📈
