How Instagram DM is Converting 40%+ of Followers to Subscribers

Hey, it's Arik.

There's a new Klaviyo feature that's building email and SMS lists for brands way faster than traditional pop-ups, and most people are sleeping on it.

It's called "Auto Replies."

I know what you're probably thinking, “another tool promising to grow your list.” But hear me out, because this meets your audience where they already are (Instagram) and converts them in the moment.

If you have thousands of people following you on Instagram who are genuinely interested in what you sell, engaging with your content, watching your stories, and commenting on your posts, then you already have HOT leads ready to make a purchase.

Unfortunately, they're stuck on Instagram. And thanks to the algorithm, you have zero control over whether they actually see your content. Instagram decides if your post shows up in their feed, not you.

But, what if you could convert those Instagram followers into email and SMS subscribers without asking them to leave the app?

What if the entire process happened right there in their DMs, and took less than 30 seconds?

That's exactly what Klaviyo's Auto Replies feature does, and I'm convinced this is one of the most underutilized list-building strategies out there.

Let me show you how it works and why you should be using it.


How This Actually Works
The concept is simple: You connect your Instagram account to Klaviyo, create a campaign that encourages people to send you a specific keyword via DM, and when they do, Klaviyo automatically replies with a message and captures their contact information.

Here's a real example of how this plays out:

You post on Instagram: "Want our complete guide to choosing the right shampoo for your hair type? DM us the word 'GUIDE' and we'll send it to you instantly."

Someone sends you a DM with "GUIDE."

Klaviyo automatically responds with the guide and asks for their email or phone number to send additional resources.

They provide their contact info, and boom, they're now on your email or SMS list.

The beauty of this approach is that they don't have to leave Instagram, remember to visit your website later, or navigate through multiple steps. It's instant gratification with minimal friction.


Why This Works So Much Better Than You'd Think
There are a few psychological reasons why Instagram DM list building converts at such high rates:

• It feels personal: Even though it's automated, receiving a DM feels more intimate than filling out a website form.

• The barrier is incredibly low: Sending a single word via DM takes two seconds. Compare that to navigating to a website, finding the signup form, entering your email, and confirming you're not a robot.

• You're providing value upfront: Instead of asking for an email in exchange for a generic discount, you're offering something specific and valuable that they actively requested.

• It leverages existing engagement: People who are already following you and engaging with your content are much more likely to take this next step than cold website visitors.


Real Use Cases That Actually Work
Let me give you some specific examples of how different types of brands can use this:

1. E-commerce brands: "DM us 'STYLE' for a personalized product recommendation quiz"
2. Beauty brands: "DM us 'ROUTINE' for a custom skincare routine based on your skin type"
3. Fitness brands: "DM us 'WORKOUT' for our free 7-day training plan"
4. Food & beverage brands: "DM us 'RECIPE' for 10 ways to use our product"
5. Pet brands: "DM us 'TRAINING' for our puppy training guide"
6. Supplement brands: "DM us 'GUIDE' for our complete supplement stacking guide"
7. Automotive brands: "DM us 'INSTALL' for step-by-step installation instructions"
8. Fashion brands: "DM us 'LOOKBOOK' for this season's complete styling guide"

The key is offering something genuinely valuable that's relevant to your audience. Generic lead magnets don't work as well because people can smell a bait-and-switch from a mile away.


The Strategy for Small vs. Large Followings
One question I get a lot is whether this only works if you have a massive Instagram following. The answer is no, it actually works at any size, but the strategy is slightly different.

If you have a smaller following (under 10K):
Your advantage is that your audience is probably more engaged. Focus on creating highly specific, valuable content that your niche actually wants. A smaller, engaged audience will convert better than a large, passive one.

• Use Instagram Stories heavily. Story engagement tends to be higher for smaller accounts, and you can add direct CTAs that tell people exactly what to DM you.

• Don't worry about going viral. Focus on consistently providing value to the followers you have and converting them into subscribers. A thousand engaged email subscribers is worth way more than ten thousand Instagram followers who never see your posts.

If you have a larger following (10K+):
Your advantage is volume. Even if your engagement rate is lower percentage-wise, you have more people seeing your content. Focus on creating scroll-stopping posts that clearly communicate the value of DMing you.

• Use Instagram Reels to reach beyond your existing followers. A viral Reel with a clear DM CTA can add hundreds or thousands of subscribers in a short period.
• Test different lead magnets and keywords to see what resonates with different segments of your audience. With a larger following, you likely have more diverse interests to cater to.

For both:
Consistency is key. Don't just do this once and forget about it. Make DM list building a regular part of your Instagram strategy. Different lead magnets, different CTAs, constant testing to see what resonates.

Getting Started
If you want to implement this for your brand, here's the simplest way to start:

1. This week: Create one valuable lead magnet that your audience would actually want. Make it specific and actionable.
2. Next week: Set up the Instagram Auto Reply in Klaviyo with a clear keyword and automated response.
3. Following week: Create 3-5 pieces of Instagram content promoting your DM keyword. Mix up the formats: feed posts, Stories, Reels.
4. Ongoing: Monitor your results, test different lead magnets and keywords, and optimize based on what's working.

You don't need to overcomplicate this. Start simple, see what works, then expand from there.

See you next Thursday,
