How to ACTUALLY Use Email & SMS to PRINT More REVENUE in 2025

If your email list keeps growing but your revenue isn’t, you’re not alone. I’ve been in the email marketing space for 7 years, and in just the last 12 months, my team has sent over 100 million emails. Across all that experience, I’ve noticed the same patterns again and again.

Most brands don’t have a list growth problem. They have an email performance problem.

So, if you want to make your emails actually convert in 2025, here are the biggest lessons that will change the game for your brand.

Lesson 1: Stop Causing Email Fatigue

The number one killer of performance is email fatigue. It’s the same principle you see in Meta ads: the higher the frequency, the worse the performance.

What does email fatigue look like?

Same subject line style week after week.
Identical layouts in every campaign.
Recycled call-to-actions.

It’s like showing up to a party in the same outfit six months in a row. Eventually, people stop noticing you.

How to Fix It: Add Variety

Rotate in different content formats and storytelling angles. Examples:

Customer story emails: Share how your product solved a specific problem. (Musicbed nails this format.)
Founder POV: Share how the brand was started or the mission behind it. (Hostage Tape used this beautifully.)
Myth-busting emails: “Did you know” angles that challenge industry misconceptions.
Product teasers: Blur out product images, hint at what’s coming, and build anticipation like a movie trailer.
Behind-the-scenes drops: Show your process, new product development, or a peek into the brand’s day-to-day.

Think of your email content like a Netflix library. No one wants to watch the same movie five times a week.

Lesson 2: Rethink Your Pop-Ups

If your subscriber growth has stalled, your pop-up is probably the problem. “Enter your email for 10% off” isn’t enough anymore.

Here’s what’s working now:

Tiered or gamified offers: Spin-to-win mechanics that feel fun without being tacky.
UGC-style pop-ups: A short testimonial plus a photo. Makes the offer feel personal and trustworthy.
Lead magnets: For premium or non-discounting brands, these work incredibly well. Example: Masiello offered turkey targets instead of a discount and converted at 45% during turkey season.

Pro Tip: Whatever your pop-up promises, deliver immediately. Your welcome flow should hit within 60 seconds.

At ASPEKT, our standard welcome flow has 3–5 emails (plus optional SMS), and we’ve seen it drive up to 40% of first-purchase revenue for new subscribers.

Lesson 3: Use Plain Text Emails

While everyone else floods inboxes with hyper-designed templates, one of the easiest ways to stand out is a plain text founder-style email.

Examples of where this works:

Product restock alerts.
A short “why we made this” founder letter.
A simple win-back nudge like, “Hey, are you still there?”

These crush because they feel real and personal. The brand becomes more than a logo. It becomes a person your subscribers trust.

To boost results even further, send from a personal name like “John from Nike” instead of just “Nike.” It feels human and typically lifts open rates.

Lesson 4: Simplify Your Automations

More flows do not equal more revenue.

I’ve audited accounts with hundreds of automations running. Dozens of welcome flows, stacked cross-sells, niche micro-segments. The result? Chaos and very little revenue.

Think of it like day trading: more screens don’t make you more money.

Focus on the Core 5 Flows:

Welcome flow
Abandonment flows (checkout, cart, browse, site)
Post-purchase flow
Win-back flow
Replenishment or subscription nudges (if relevant)

Make these flows tight and intentional:

No dead-ends.
No overlapping logic.
Clean exclusions (like suppressing buyers from your welcome flow).

Don’t “set it and forget it.” Instead: set it, watch it, tweak it, repeat.

Lesson 5: Segment Smarter

Segmentation isn’t about slicing your list into a million micro-groups. It’s about knowing who’s worth emailing right now.

Keep it simple:

Last engaged 30 days.
Bought in the last 60 days, but not again.
Viewed product X but didn’t purchase.

Then, match your messaging to that segment’s mindset, not just their behavior.

For example:

Someone who viewed a product but didn’t buy needs social proof and reassurance.
Someone who purchased once but hasn’t reordered needs replenishment or bundle offers.

As for frequency, 2–4 emails per week is fine if you rotate content and suppress unengaged subscribers. If you blast everyone with the same message, you’ll burn your list faster.

Lesson 6: Use SMS as the Closer

If email is the drumbeat, SMS is the knockout punch.

We use SMS to:

Recover abandoned carts.
Launch fast-moving drops.
Send last-chance “discount ends tonight” reminders.

But SMS is not email. Keep it short, sweet, and low frequency. Think high-intent nudges, not daily spam.

One tactic we love: pair your welcome email with an SMS 10 minutes later. It works across Postscript, Klaviyo SMS, and Omnisend.

SMS doesn’t need to be constant. It just needs to matter when it arrives.

Quick Recap

If your email list is growing but your revenue isn’t, here’s your action plan for 2025:

Add variety to your emails to fight fatigue.
Upgrade your pop-ups beyond basic discounts.
Mix in plain text founder emails.
Simplify automations down to the core five flows.
Segment smarter, not harder.
Use SMS strategically as the closer.
