Is MailerLite Tracking Your Email? How to Block It

Every newsletter you open from a business using MailerLite sends a silent report back to the sender — your approximate location, your device, your email client, and the exact second you read it. You opted in to receive the email. You did not opt in to be profiled every time you open it.

Key Takeaways

• MailerLite embeds an invisible tracking pixel in every campaign email by default, firing when your email client loads images and reporting your IP address, device type, and timestamp to the sender.
• Click tracking operates independently from open tracking — disabling one does not disable the other, and MailerLite rewrites every link to route through its own servers before redirecting you.
• Over 1 million businesses worldwide use MailerLite, meaning a significant share of the newsletters in your inbox are sending this data without any separate consent for tracking.
• MailerLite is headquartered in Vilnius, Lithuania, putting it under GDPR jurisdiction, yet the platform places responsibility for subscriber consent on senders — not on itself.
• Gblock blocks both the tracking pixel and the link rewriting, letting you read MailerLite newsletters without being logged.

What Is MailerLite?

MailerLite is an email marketing platform used by over 1 million businesses to send newsletters, promotional campaigns, and automated email sequences. Unlike sales tools such as HubSpot or Outreach that track individual prospect behavior, MailerLite operates at mass scale — your dentist's appointment reminder, your favorite coffee brand's weekly digest, your local gym's promotions. The recipients did something reasonable: they subscribed to receive those emails. The tracking that comes with them is a different matter entirely.

The platform competes with Mailchimp, Klaviyo, and Constant Contact. All of them use the same core tracking infrastructure. MailerLite's positioning as a budget friendly, privacy forward alternative makes its default on tracking especially worth understanding.

How Does MailerLite Open Tracking Work?

MailerLite open tracking works by embedding an invisible 1x1 pixel image into the HTML of every campaign email. When your email client renders the message and loads that image, your client sends an HTTP request to MailerLite's servers. That request is logged as an "open" and captures four pieces of data: a timestamp, your IP address, your device type (desktop, mobile, tablet), and your email client (Gmail app, Apple Mail, Outlook).

From the IP address, MailerLite generates an approximate geographic location. The platform surfaces this as an "Opens by location" map in the sender's analytics dashboard — a feature MailerLite explicitly markets as a selling point. If you opened that newsletter from your home WiFi, the sender sees your neighborhood. If you opened it from your office, they see your company's location.

One wrinkle: Apple Mail Privacy Protection now prefetches email content through Apple's proxy servers before users even open messages. According to MailerLite's own analysis, roughly 58% of email opens in Apple Mail environments now appear as opens regardless of whether the recipient actually read the email. The pixel still fires — Apple just fires it first, making location data less reliable but not eliminating the tracking infrastructure itself.

Does MailerLite Track Every Link You Click?

Yes — and this is the part most people miss. MailerLite click tracking is completely separate from open tracking. When you disable opens tracking on a campaign, click tracking remains active unless you disable it independently.

Every link in a MailerLite campaign is rewritten before the email is sent. Instead of linking directly to the destination, the link becomes a MailerLite redirect URL. When you click, your browser first hits MailerLite's servers, which log the click (including which specific link, your device, and timestamp), then redirect you to the original destination.

MailerLite acknowledges this in its help documentation, where senders can toggle opens and click tracking independently. The platform also supports Google Analytics integration, appending UTM parameters to tracked URLs — meaning clicking a link in a MailerLite newsletter can trigger a second layer of tracking once you land on the destination website.

The implication is straightforward: even if you never load images (which blocks the pixel), clicking any link still tells MailerLite — and potentially the sender's analytics stack — that you engaged, when, from what device, and from which link.

What Is Engagement Scoring and Why Does It Affect You?

MailerLite uses open and click data to calculate subscriber "engagement scores." Subscribers who have not opened or clicked within a defined window get classified as inactive, and senders can configure automatic list cleaning that removes low engagement subscribers entirely.

This creates an odd feedback loop: if you block open tracking to protect your privacy, your engagement score drops. If it drops low enough, you get removed from a list you voluntarily joined. You may miss a warranty renewal notice, a banking alert, or a community newsletter because the platform classified your silence as disengagement rather than a privacy preference.

The consent problem here is structural. As MailerLite's GDPR guidance makes clear, responsibility for obtaining subscriber consent for tracking sits with the sender, not with MailerLite. Most senders are not obtaining separate consent for behavioral tracking beyond the opt in to receive email. Opting in to receive emails and consenting to be profiled every time you read one are different acts — but the industry has largely collapsed them into a single checkbox.

How Can You Tell If an Email Uses MailerLite Tracking?

You can inspect the HTML source of any email. In Gmail, open the email, click the three dot menu in the top right, and select "Show original." Search the raw source for mailerlite.com or click.mailerlite.com. A tracking pixel will appear as an <img> tag with a MailerLite URL. Rewritten links will show as anchor tags pointing to MailerLite redirect domains before the actual destination.

Why Email Users Should Care

If your inbox contains newsletters, promotional emails, or automated sequences from small businesses, bloggers, or independent creators, a large share of them almost certainly run on MailerLite. The platform's growth among independent publishers means exposure is widespread and largely invisible — unlike consumer facing brands, smaller senders rarely disclose their email infrastructure in their privacy policies.

Every open you are tracked on builds a behavioral record: what time of day you read email, where you are when you do, what device you use, and which topics or promotions you click. Across dozens of MailerLite powered lists, that data accumulates into a surprisingly detailed profile. None of it requires a data breach to reach your sender — it is the product working as designed.

How to Block MailerLite Tracking

Gblock is the most complete solution for Gmail users. It blocks the tracking pixel before it fires, stripping the open tracking signal entirely. It also handles link rewriting — you click through to the actual destination without your click being logged by MailerLite's redirect servers. You read the newsletter; the sender gets no behavioral data about when, where, or how you read it.

Other partial options exist but come with real tradeoffs. Disabling automatic image loading in Gmail (Settings → General → Images → "Ask before displaying external images") blocks pixels but also strips all images from every email, making most newsletters difficult to read. Unsubscribing removes you from the list entirely — not always what you want when the content itself is valuable.

Gblock handles both tracking vectors (pixel and link rewriting) without changing how the email looks or requiring you to opt out of content you actually want. The same extension also blocks Mailchimp tracking, Klaviyo tracking, and dozens of other email marketing platforms that use the same pixel architecture.

MailerLite's tracking is not unusual — it is standard email marketing practice. But standard is not the same as invisible, and you do not have to accept it by default.
