Today’s customers value seamless experiences just as much as a product’s quality and price. In fact, 73% of them consider experience an important factor in their purchasing decisions, behind price and product quality. 

And where do these experiences often begin? Right in their inbox or WhatsApp chats.

Email and WhatsApp have evolved from simple communication tools to powerful channels for brands to connect with their audience. But these channels are also flooded with businesses offering similar products, services, and, often, similar messages.

How can you stand out? 

From catchy subject lines to one-click WhatsApp conversations, you can play to each channel’s strengths and engage with customers. This doesn’t have to put a dent in your budget. ZEPIC offers some free email marketing and WhatsApp marketing tools to make your life easier. Let’s learn more about these and how they can help you.

Free Email Marketing Tools

Throughout the years, many have claimed that email marketing is dead. However, this channel is far from finished. Email marketing revenue worldwide is expected to reach $17.9 billion by 2027, and 41% of marketers say email is their most effective channel, way ahead of social media and paid search.

That being said, an average person receives hundreds of emails in a week. How can you give your campaigns a fighting chance? This is where effective subject lines play a crucial role.

Generic subject lines are more likely to be lost in the customer’s inbox.

“47% of email recipients will open an email based on the subject line alone, and 69% report spam based on the subject line.”

We understand how confusing it can be to decode what will work and what will push your email to spam. That’s why we’ve come up with two email free tools that’ll help you ace the subject line game. 

Subject line Generator

ZEPIC’s free email subject line generator is powered by Zenie AI. 

Zenie AI was trained on thousands of subject lines with more than 60% open rates to give you a subject line that converts.

All you have to do is type in what you want and let Zenie work its magic. 

Benefits of Using Subject Line Generator:
  • Save hours brainstorming subject lines that convert
  • Leverage AI trained on proven high-performing subject lines
  • Instantly generate multiple options for A/B testing
  • Improve open rates with psychologically compelling phrases
  • Stand out in a crowded inbox with a fresh, engaging subject line

Subject Line Tester

From character limit to emoji use, many factors influence a subject line’s effectiveness.

“Subject lines with fewer than 70 characters have the highest open rates because they are optimized for mobile device display.” 

ZEPIC’s free email subject line tester was developed to help you ensure your subject line meets the various parameters and increase open rates.  

Once you input your subject line, the tool tests your subject line and gives you a score based on,

  • Length
  • Personalization
  • Emoji use
  • Punctuation use
  • Spam triggers
  • Capitalization
  • FOMO elements
  • Readability and sentiment
  • Word count
  • Negative words

The tool doesn’t just give you a cumulative score; it evaluates your subject line, and it gives a rating for each parameter. This will help you get a clear picture of what needs to be improved to increase your open rates. 

Benefits of Using the Subject Line Tester:
  • Identify and fix issues before sending your campaigns
  • Learn what makes effective subject lines through detailed feedback
  • Reduce the risk of landing in spam folders
  • Optimize for mobile devices, where most emails are opened
  • Track improvement over time as you refine your subject line skills
  • Increase ROI on your email marketing efforts through higher open rates

Free WhatsApp Marketing Tools

Since WhatsApp offers a more personal and direct way to communicate with customers, it has become quite popular among brands. WhatsApp Business was downloaded 152.1 million times in 2024, which shows almost every business loves using the platform.

Desperate times call for desperate Google/Chat GPT searches, right? "Best Shopify apps for sales." "How to increase online sales fast." "AI tools for ecommerce growth."

Been there. Done that. Installed way too many apps.


But here's what nobody tells you while you're doom-scrolling through Shopify app reviews at 2 AM—that magical online sales-boosting app you're searching for? It doesn't exist. Because if it did, Jeff Bezos would've bought (or built!) it yesterday, and we (fellow eCommerce store owners) would all be retired in Bali by now.


Growing a Shopify store and increasing online sales isn’t easy—we get it. While everyone’s out chasing the next “revolutionary” tool/trend (looking at you, DeepSeek), the real revenue drivers are probably hiding in plain sight—right there inside your customer data.
After working with Shopify stores like yours (shoutout to Cybele, who recovered almost 25% of their abandoned carts with WhatsApp automation), we’ve cracked the code on what actually moves the needle.


Ready to stop app-hopping and start actually growing your sales by using what you already have? Here are four fixes that will get you there!

Fix #1: Convert abandoned carts instantly (Like, actually instantly)

The Painful Truth: You're probably losing about 70% of your potential sales to cart abandonment. That's not just a statistic—it's real money walking out of your digital door. And looking for yet another Shopify app for abandoned cart recovery isn't going to fix it if you're not getting the fundamentals right.

The Quick Fix: Everyone knows you need multi-channel recovery that hits the sweet spot between "Hey, did you forget something?" and "PLEASE COME BACK!" But here's the reality—most recovery apps are a one-trick pony. They either do email OR WhatsApp, not both. And don't even get us started on personalizing offers based on cart value—that usually means toggling between three different dashboards while praying your apps talk to each other.

Enter ZEPIC: This is where we come in. With ZEPIC's automated Flows, you can:
Launch WhatsApp recovery messages (with 95% open rates!)
Set up perfectly timed email sequences (or vice versa)
Create personalized recovery offers not just on cart value but based on your customer’s behavior/preferences
Track and optimize everything from one dashboard

Fix #2: Reactivate past customers today

The Painful Truth: You're probably losing about 70% of your potential sales to cart abandonment. That's not just a statistic—it's real money walking out of your digital door.
