You probably know mailerlite for its clean interface and generous free tier, but it has evolved into a powerhouse that rivals high-end enterprise tools. Beyond simple newsletters, you can now use mailerlite to build full-scale websites with password-protected pages, sell digital products via stripe with 0% commission, and even talk to your subscriber data using a dedicated AI assistant via the Model Context Protocol (MCP).
I discovered that its automation builder now supports up to three simultaneous triggers for a single workflow, allowing for complex customer journeys that used to require a $200/month subscription elsewhere.
Whether you’re looking to sync segments directly with Facebook Custom Audiences for hyper-targeted ads or use the “RSVP” block to manage event registrations without a third-party app, these hidden features turn a simple email tool into a complete digital marketing command center for your business.
7 Advanced Features You’re Probably Missing:
In my 10 years of managing email lists, I’ve seen platforms bloat until they’re unusable. When I first tested the “New” mailerlite interface, I was worried they’d lose their signature simplicity. Instead, they tucked some of the most powerful features I’ve ever used just beneath the surface.
1. The "Talk to Your Data" AI Assistant:
One of the most “insider” updates I’ve seen recently is the mailerlite MCP (Model Context Protocol) server. I discovered this while trying to pull a quick report for a client who wanted to know which subject lines worked best in 2025. Instead of manual exporting, you can now connect your account to AI tools like ChatGPT.
I literally typed, “Which of my segments had the highest click rate last month?” and the AI pulled the data directly from my dashboard. According to MailerLite’s 2026 Trends Report, treating your data like a “teammate” via AI is the standard for staying competitive this year.
2. Multi-Trigger Automations:
In the past, an automation could only start if one specific thing happened (like someone signing up). When I was building a re-engagement campaign for a SaaS client, I realized we needed more nuance. On the Advanced plan, you can now set up three different triggers for one workflow. For example, a user can enter your “VIP” sequence if they click a specific link, or if they spend over $100, or if they update a custom field. This prevents the “spaghetti mess” of having 50 different small automations running at once.
3. Selling Products with 0% Transaction Fees:
I once had a conversation with a creator who was losing 10% of every sale to platform fees. I showed them the “Sites” feature in mailerlite. If you connect your Stripe account, you can sell ebooks or coaching sessions directly on a mailerlite landing page. The “insider” detail here? mailerlite takes 0% commission on your sales. You only pay the standard Stripe processing fee.
4. The "Secret" RSVP Block:
Many users don’t realize they can manage event sign-ups without using Eventbrite. In the drag-and-drop editor, there is an “Event” block. I found a “hack” where you can remove the date and location fields and use the button specifically to add clickers to a “Coming to Webinar” group. It’s the cleanest way to segment your “hot” leads without making them fill out another form.
5. Password-Protected Pages:
When I tested this for a private resource library, I was shocked at how well it worked. You can build a page on the mailerlite website builder and toggle on “Password Protection.” This is perfect for “hidden” bonuses for your subscribers. It gives that “premium member” feel without the cost of a dedicated membership site like Kajabi.
6. Facebook Custom Audience Syncing:
This is a game-changer for your ad spend. Instead of manually uploading CSV files to Meta (which is a privacy nightmare and quickly becomes outdated), you can sync your mailerlite segments directly. When someone unsubscribes from your list, they are automatically removed from your Facebook “Retargeting” ad set. This ensures you aren’t wasting money showing ads to people who no longer want to hear from you.
7. Clean List "Auto-Pruning":
Poor deliverability usually starts with a “stale” list. In the automation settings, you can create a rule that says: “If a subscriber hasn’t opened an email in 6 months, move them to the Unsubscribed group.” While it hurts to see your subscriber count drop, MailerLite’s 2025 Benchmarks show that global unsubscribe rates rose to 0.22% as Gmail and Yahoo tightened their filters. Aggressive pruning is actually what keeps you out of the spam folder.
💡 Pro Tip: The "Resend to Unopens" Trap
Many experts will tell you to always resend your campaign to those who didn’t open it. The Pitfall: If you do this with the exact same subject line, Gmail’s filters often flag it as duplicate spam. My Expert Advice: When using the “Auto-resend” feature in mailerlite, always change the subject line to something more urgent (e.g., “In case you missed this…”) and wait at least 48 hours. This simple tweak usually bumps my total open rates by an extra 8-12% without hurting my sender reputation.
Conclusion & Next Steps:
mailerlite is no longer just “the simple tool.” It’s a sophisticated ecosystem that can handle your website, your store, and your advanced CRM needs. If you’re still just sending basic newsletters, you’re leaving money—and data—on the table.
Your Action Plan:
Pick one segment of your list today and set up a re-engagement automation using the “Date-based” or “Custom Field” trigger to check in on your inactive subscribers. It’s the fastest way to see the power of these advanced features in action.
Frequently Asked Questions (FAQ):
1. Can I really sell digital products with 0% commission on the free plan?
Yes, I’ve confirmed that even on the free tier, you can sell digital products like ebooks and PDFs without paying a transaction fee to mailerlite. While you still have to pay the standard processing fees charged by Stripe (usually $2.9% + 30c), mailerlite does not take an additional cut of your revenue. In my experience, this makes it an incredible “bootstrap” tool for creators who want to test a product idea without committing to the high monthly costs of platforms like Shopify or Gumroad.
2. How does the password protection feature work for websites?
I discovered that you can easily lock individual pages on your mailerlite website by toggling the “Password protection” option in the page settings sidebar. When a visitor tries to access that specific URL, they are greeted by a customizable login screen where they must enter the password you’ve set. It’s a “pro” move for creating simple member-only resource libraries or “secret” sales pages that you only want your loyal email subscribers to see.
3. What is the limit for multi-trigger automations?
On the Advanced plan, you can set up to three separate triggers for a single automation workflow, which is a massive upgrade from the old “one trigger” limit. This means a subscriber could enter your welcome sequence if they join a group, or if they click a specific link, or if a custom field in their profile is updated. When I’m building complex funnels, this feature is a lifesaver because it allows me to consolidate three different entry points into one streamlined customer journey.
4. Do I need a third-party app to sync my list with Facebook ads?
No, you don’t need Zapier or any expensive middleware because mailerlite has a native Facebook Custom Audiences integration built right into the Advanced plan. Once you connect your accounts, you can select specific segments that will automatically sync with your Meta Ads Manager in real-time. I’ve found this “insider” feature to be the best way to stop wasting money on ads shown to people who have already purchased your product or unsubscribed from your list.
5. Can I automate the process of cleaning my email list?
Absolutely, and I highly recommend doing this to protect your sender reputation. You can set up a “Re-engagement” automation that triggers when a subscriber has been inactive for a specific period, such as six months. If they don’t engage with your “win-back” email, you can use an “Action” step to automatically move them to an “Unsubscribed” or “Clean Up” group. According to MailerLite’s 2026 Deliverability Guide, keeping a “lean” list is the number one way to ensure your emails stay in the primary inbox rather than the promotions tab.
