The Best Free Email Marketing Plan: Send Up to 80,000 Emails a Month at No Cost

Professional email marketing no longer requires an upfront investment.

There is a stubborn myth in digital marketing: that doing it “properly” means opening your wallet from day one. Paid ads, pricey software subscriptions, a designer on retainer. For a lot of small businesses, freelancers, and creators, that assumption is enough to stop them from ever sending their first campaign.

Email marketing is the clearest proof that the myth is wrong. It’s still one of the highest-return channels in all of digital — industry studies routinely put the return somewhere around $36 to $42 for every dollar spent — and it’s a discipline you can start, and even scale, without paying anything. If you want the evidence, look no further than the free plan from Mailrelay, which gives you room to grow that most “free” plans simply don’t.

The goal of this article is straightforward: to show that you don’t need a budget to build a professional email marketing operation, and to explain why Mailrelay tends to be the logical choice once you factor in scalability and real human support.

Why “free” usually means “crippled”

Almost every email platform offers a free tier. The problem is what happens once you read the fine print. Free plans are typically designed as trials in disguise — just generous enough to get you hooked, and just restrictive enough to push you onto a paid plan the moment your list starts to grow.

You’ll recognise the usual limitations:

• Tiny contact caps. A few hundred subscribers, sometimes fewer.
• Low monthly send limits, or worse, daily send caps that stop you emailing your whole list at once.
• Paywalled features. Automation, detailed statistics, or removing the provider’s logo are locked behind an upgrade.
• Forced branding. Your newsletters go out with someone else’s logo in the footer, which quietly undermines how professional you look.
• No real support. On many free tiers, if something breaks, your only option is a help centre article.

None of this is inherently dishonest — companies need to make money. But it does mean that “free” often translates to “not usable for anything serious.” That’s exactly the gap Mailrelay set out to close.

What makes Mailrelay’s free plan different

Mailrelay’s free account is built around a simple idea: give people enough headroom that they can actually run their marketing, not just kick the tyres. Here’s what it includes at no cost:

• Up to 80,000 emails per month. This is the headline number, and it dwarfs most competitors.
• Up to 20,000 contacts. The largest free contact database on the market, so your list can grow for a long time before you ever hit a wall.
• No daily sending limit. You can email your entire list in one go, whenever you want — no artificial throttling.
• Full features unlocked. Automation and workflows, real-time statistics, the visual editor, SMTP server, and API access are all available on the free plan, not held hostage behind a paywall.
• No forced branding. Your emails don’t carry a “sent with Mailrelay” logo, so your brand is the only one your subscribers see.

That combination is unusual. Most platforms make you choose between volume and features on a free plan. Mailrelay gives you both.

How the free plans actually compare

Numbers make the difference obvious. Here’s how the leading free tiers stack up (limits on these plans change often, so it’s always worth confirming the current figures on each provider’s own pricing page before you commit):

Read down the “emails per month” column and the story tells itself. Where a growing business would exhaust most free plans in a single send, Mailrelay’s 80,000-email allowance leaves genuine room to breathe. And several competitors have been tightening their free tiers recently rather than loosening them, which makes that headroom even more valuable.

Beyond volume: the tools that make you look professional

A big free allowance is worth little if the emails themselves look amateurish. This is where Mailrelay’s free plan quietly earns its keep.

A visual editor with built-in AI. You don’t need design skills to produce a clean, responsive newsletter. Mailrelay’s drag-and-drop editor includes integrated AI to help you design and write, so a polished campaign is a matter of minutes rather than an afternoon of wrestling with HTML.

Automation and workflows — for free. Welcome sequences, follow-ups, re-engagement flows: the kind of “set it and forget it” marketing that usually signals a serious operation. Mailrelay lets you build workflows with multiple actions, conditions, and tags, and it’s genuinely multichannel — you can combine email and SMS in the same flow. On most platforms, automation of that depth is a paid-tier feature. Here it’s included from the start.

Real-time analytics. You can’t improve what you can’t measure. Mailrelay gives you complete statistics as they happen — opens, clicks, bounces, heat maps showing exactly where subscribers tapped, and which links pulled the most engagement. That’s the feedback loop that turns guesswork into a repeatable, improving strategy.

Deliverability that scales to millions. Sending a beautiful email is pointless if it lands in spam. Mailrelay operates its own dedicated IP ranges and uses delivery algorithms specifically built to get messages into the inbox. This is the same infrastructure that makes it a serious option for large organisations sending millions of emails — so the deliverability foundation you rely on as a beginner is the same one that will carry you at scale.

Support in your own language, from a European company

One of the most underrated differences shows up the moment something goes wrong. On many free plans, support means a search box and a stack of help articles.

Mailrelay is a European (Spanish) company, and it offers real human support — by phone, live chat, and ticket — available even to free-plan users, in your own language, including Spanish and English. That matters more than it sounds. When a campaign isn’t sending or your deliverability dips before an important launch, talking to a person who can actually help is the difference between a quick fix and a lost day.

Being EU-based also means your data sits on European servers under strict data-protection rules — a genuine consideration for any business that cares about GDPR compliance and where its subscriber data lives.

Why it’s the logical long-term choice

Here’s the part that separates a smart starting point from a smart decision. Choosing an email platform isn’t only about today’s list of a few hundred contacts — it’s about not having to migrate everything the moment you succeed.

With Mailrelay, the free plan isn’t a walled-off trial; it’s the bottom rung of the same ladder. The editor, the automations, the analytics, and above all the deliverability infrastructure are the exact tools that power its enterprise-grade, high-volume sending. So as your audience grows from hundreds to tens of thousands and beyond, nothing about your workflow has to change. You’re not starting over — you’re just turning up the volume.

That’s what “scalable” really means: a tool you can commit to now without regretting it later.

Getting started

There’s no clever trick to it, and no credit card required. You create a free account, import or start building your contact list, design your first campaign in the visual editor, and send. From there, layer in automations and start reading your real-time stats to sharpen every send that follows.

The barrier to professional email marketing was never money. It was the belief that you needed money. With a free plan that offers up to 80,000 emails a month, 20,000 contacts, full features, and human support, Mailrelay removes that barrier entirely — and gives you a platform you won’t outgrow.

Start free, send professionally, and let the results make the case for you.
