Most businesses run paid social and email marketing as if they are two separate things. The ads team does the ads. The email team does the emails. They might share results at a monthly meeting. But the two rarely work together in a planned way.
This is a missed opportunity. Paid social and email are most powerful when they are designed to support each other. When they work together, each one makes the other more effective. When they work in isolation, you are getting less than half of what either can do.
They Serve Different People at Different Times
Paid social is best at reaching new people. People who have never heard of you. People who are scrolling and discover your brand by accident. It is also good at re-engaging people who visited your site but did not buy.
Email is best at reaching people who already know you. People who have bought before. People who signed up for your list because they were interested. They are warmer. They trust you more. They need less convincing.
These are two very different audiences. Treating them the same way does not make sense. A full-funnel approach recognises that cold audiences (paid social) and warm audiences (email) need different messages at different times.
The businesses that grow fastest understand that paid social builds the audience and email converts and retains them.
Paid Social Grows Your Email List
One of the most valuable things paid social can do is grow your email list. A campaign that drives people to sign up for a lead magnet, a free resource, a discount, or a newsletter puts new contacts into your email system.
These people are cheaper to market to in the long run. Email has no cost per impression. No auction. No algorithm deciding who sees your message. Once someone is on your list, you can reach them directly.
This means a Meta campaign that generates email sign-ups might not look impressive in terms of direct revenue. But the value shows up over the following months as those subscribers receive emails, build trust, and eventually buy.
Cost per lead through paid social looks very different when you factor in the long-term value of an email subscriber versus a one-time buyer.
Use Email Lists to Improve Your Paid Social Targeting
Your email list is more than a marketing channel. It is a data asset that can make your paid social ads significantly better.
When you upload your email list to Meta, it creates a custom audience from the people on that list who also have Meta accounts. You can then show ads specifically to those people. This is a warm audience. They know you. They are more likely to respond. Your cost per result is usually lower than cold prospecting.
You can also use that email list to create a lookalike audience. Meta finds people who are similar to your email subscribers and shows them your ads. Lookalike audiences built from high-quality email lists often outperform those built from general website traffic because the source data is stronger.
Your existing customers and subscribers are the best clue the algorithm has for who else to find. Sharing that data with Meta makes your ads smarter.
Suppress Email Subscribers from Cold Prospecting
Here is a mistake that wastes a surprising amount of ad spend.
When you run a cold prospecting campaign, you are trying to reach people who have never heard of you. But if your email subscribers are inside your target audience, they will see those ads too. You are paying to reach people who already know you with messaging designed for strangers.
This is called audience overlap. It can be fixed with a suppression list. You exclude your email subscribers from your cold prospecting campaigns. This means your cold prospecting budget goes only to genuinely new people. Your subscribers get messaging through email, which costs nothing per send.
Suppression lists are a small technical step with a real impact on efficiency. Most businesses that have never set them up are wasting a portion of their prospecting budget on people who should be in a different part of the funnel.
Use Email to Follow Up on Ad Clicks
Here is a powerful combination that very few businesses use fully.
When someone clicks your paid social ad and lands on your page but does not buy, what happens? Usually, a retargeting ad shows up later. That is fine. But email can work alongside it.
If that visitor had already given you their email before, you can send them an email within 24 hours of their visit. You know they were interested. You know what they looked at. A timely email referencing that interest converts at much higher rates than a generic retargeting ad.
This requires connecting your ad pixel data to your email platform. It requires some setup. But once it is running, it creates a powerful follow-up loop. The ad drives the visit. The email closes the deal. Together they do something neither can do alone.
How to Start Connecting the Two
You do not need to do everything at once. Here is a simple starting sequence.
First, upload your email list to Meta and create a custom audience. Exclude that audience from your cold prospecting campaigns.
Second, create a campaign specifically for that email list with warm audience messaging. This is different from your cold ads. It can reference that they already know you. It can make a more direct offer.
Third, if your volume allows, create a lookalike audience from your best email subscribers or customers. Test it against your existing prospecting audience.
Fourth, set up a re-engagement email sequence for people who click your ads but do not convert. Even a simple two or three email sequence adds meaningful lift.
The Bottom Line. How Do You Work Paid Social and Email Marketing Together.
Paid social and email marketing are not competing channels. They are designed for different parts of the customer journey. When they share data and strategy, both of them perform better.
Paid social brings in new people and re-engages visitors. Email nurtures and converts. Together they build a system that is more efficient and more resilient than either one alone.
Before your next campaign, ask yourself:
- Have you uploaded your email list to Meta as a custom audience?
- Are your email subscribers excluded from your cold prospecting campaigns?
- Do you have a specific ad campaign for your warm email audience with messaging that matches where they are in their relationship with you?
- Is there an email follow-up sequence for people who click your ads but do not convert?
- Do you know how many of your email subscribers came from paid social campaigns?
Making these two work together is one of the most cost-effective improvements a scaling business can make.
