Don’t lose hard-earned leads to inactivity.

This blog will provide you with a quick guide on how to effectively build cold email sales campaigns to re-engage contacts without wasting time and money.

You’ll get email templates, a send schedule, tips on tagging and segmenting using CRM data, as well as ideas on how to use automation to optimize your re-engagement results.

How to Write a Cold Email for Sales

Lost SalesLeads that have lost interest (gone “cold”) aren’t gone forever. It’s just going to take some attention to detail, and you’ll see a positive return-on-investment (ROI) on existing contacts instead of paying big bucks for new ones.

These leads wanted your help once. It’s time to make them remember the good old days.

When it comes to contact ROI, remember the words of one of America’s greatest poets “You don’t know what you got, til’ it’s gone.” (Cinderella, Long Cold Winter, 1988).


Cold sales email campaigns need to take big swings on personalization, targeting, subject lines, pre-headers, and copy. Ensure you’re using any customer data at your disposal to make maximum impact. Get their attention, and keep it.

Let’s start with a few examples of cold emails to a potential client from Keap’s content team.

Day 181: Exclusive Content Offer

This example begins the day after a user has been unengaged for 180 days (6 months). You will send 4 emails, with each new message sent every 3 days.

To get your contacts’ attention, you need to put the most enticing offers front and center in your cold email introduction. Offer access to targeted content and resources.

Using CRM data, you can easily segment contacts by interest, thereby achieving as much as 100.95% higher open rates than non-segmented campaigns.

Re-engagement messaging shouldn’t be complicated. Curate the content and use CRM data to target and personalize their content.

Highly Personalized OffersDid you know 52% of customers expect offers to always be personalized — up from 49% in 2019?

So if your re-engagement campaigns are one-size-fits-all, you’re just wasting time, energy, and money.

Remember, you’re looking to make a big impact on a small target. When you try to please everyone, you delight no one.

Day 184: New Features, Plans, and Products

After months of being cold, your contacts may have missed some exciting changes in your company. Lead with your most exciting release, and tease a few updates from the last six months.

But ensure you’re optimizing interest from their first glance at your subject line.

Let your audience know immediately if you’ve launched new products, upgraded features, or fixed some big bugs. Be clear in your cold email introduction that there are big things on offer.

Remember that even great campaigns only see a 20.94% open rate, so non-targeted email blasts are rarely worth your time.

Send multiple targeted emails in quick succession (2-3 days apart) for best results.

Day 187: Top Picks and Fan Favorites

Best-of compilations are always a hit (even Bowie had Changesone.) So if your audience isn’t excited by your monthly blogs, maybe all your top content in place will do the trick.

A collection of your highest performing content is a high-value offer. When you remove the pain point of searching for relevant content, you increase the likelihood of engagement bigtime!

Best-of lists perform well, but making a single generic list vastly limits your results. Using CRM data on contacts can target customers by their interests and even dynamically populate the individual selections.

This means you can send hyper-specific resources to each cold contact and optimize the likelihood of re-engagement.

Day 190: Sorry to See You Go (Last Chance)

You’ve reached the end of the road. At some point, contacts simply aren’t coming back. Your best bet at this point is to separate on good terms and have faith that you’ll reconnect when your offerings are a better fit for the client.

Subject line: Bye-bye. We’ll see you later!
Pre-header: Bye-bye, friend.

Some entrepreneurs will continue to flog cold leads over and over. The thought process is; as long as they haven’t unsubscribed, keep selling.

But if you irritate a cold contact, they may report you as spam or even leave negative reviews. Be kind to your contacts (even as they leave), so they always feel welcome to return.

This campaign template is an excellent baseline for any business. We recommend looking over your contact lists, creating segments based on user data, and building multiple (3-5 is plenty) targeted campaigns for best results.

Knowing the Reasons Your Contacts Have Gone Cold

If a lead isn’t clicking your CTAs or even opening your emails, they’ve gone cold.

It will take more than your typical marketing blast to warm them up. You’ll need to use whatever data you have on these contacts to target each audience segment appropriately.

You can easily tag and target your prospects and campaigns if you have a CRM with customer data. Remember that even great campaigns only see a 20.94% open rate, so non-targeted email blasts are rarely worth your time.

The ROI on Cold Sales Email Campaigns

A contact, even an unengaged one, represents effort and expense on your part. You had to get their attention, convince them to offer their data, and develop marketing and sales strategies to target them.

That’s an awful lot of personal investment to let walk out the door.
