7 Best Email Marketing Software to Grow Your Revenue

Email marketing is still one of the most powerful tools for turning any website into an online business. So what are the best email marketing software service providers? The answer depends on your budget, marketing needs and overall goals.

From sending out a simple weekly or monthly newsletter to your followers, to building out advanced full featured user journeys to convert subscribers into buyers, in this detailed software review I’m going to break down your best options for different and specific use cases.

Essential email marketing features to look for:

1. Deliverability of your emails

You want your emails hitting the inbox, not the spam folder or the promotions tab in Gmail. Deliverability of your emails comes down to a few things. Images, what words you use in your copy (“make money online” is a sure fire way to land in the promotions tab or spam folder!) and your overall domain reputation.

2. Email autoresponder

An autoresponder, often called a “workflow” on many platforms is simply automated emails someone gets when they sign up to your list or trigger an action.

3. Email marketing funnel

With email marketing you can create an email funnel for your list. A funnel is a series of emails someone gets with the end goal to convert them to buy. More advanced software provides detailed funnel construction, if/or functions and user behavior.

4. List separation

List separation means you can create different funnels for different types of content. Maybe you have subscribers signing up on a video where you talk about how to start a YouTube channel and another video where you talk about personal finance for solo creators.

5. Affiliate Marketing Friendly

Affiliate marketing is promoting products and services for a commission. It’s one of the most effective ways to monetize your email list yet a few email service providers frown on affiliate marketing. Instead, some providers want you to only promote your website, videos and offers where the email is providing value.

Convert Kit – Best for content marketers (bloggers, Youtubers etc)

Convert Kit was made for bloggers and YouTubers who engage in affiliate marketing and who also sell their own digital products like courses and ebooks. They are my top choice for both YouTubers and bloggers because they have the right mix of deliverability and features content marketers need.

Specifically, Convert Kit is designed for you to create a product funnel. They have a unique built in tagging system so you can separate your list into various segments and behaviors. Those who bought, those who did not, those who opened the email those who did not.

Sales funnels

You can also create different funnels with one account with ease. For example, I could set up a free “how to start a blog” email course and put opt-in forms on relevant pages here. I could also create an “affiliate marketing for beginners” course and put different opt-in forms on different pages and posts.

Those are two similar audiences so broadly speaking, they would both be interested in my content but I could create a higher value offer for both groups. It’s this funnel centric nature that makes Convert Kit so popular.

Products

Kit allows you to create simple sales pages and your host digital products on their platform like checklist, cheat sheets, ebooks and so forth. So if you’re looking for a simple way to have both an email list and sell low ticket items Kit is not a bad choice for that.

Newsletter

Finally, Kit is an excellent choice if you want to start a simple weekly email newsletter website. With high converting templates and solid deliverability, Kit makes it incredibly easy to send out a quality newsletter.

Their “newsletter” tier allows for 10,000 subscribers for free. No limits on email sends. Sure, you don’t get automations but if you want to grow a newsletter to 10k subscribers then Kit allows you to do so completely for free.

Pros and Cons

Active Campaign – The powerful professional choice

If email marketing is the life blood of your business, if it’s what’s driving your sales more than anything else then you need to seriously look at moving over to Active Campaign (sorry don’t mean to be too hyperbolic, but that’s why you’re here because you trust me).

Active Campaign email marketing software is a very robust solution for professional content marketers and small businesses. The system features many different templates and optimization tools that allow you to segment and track your audiences behavior easily.

You can send highly personalized emails based on customer preferences and behavior as well as manage all phases of the user experience from the welcome email to the funnel process. Active Campaign also lets you send emails that based on local time, SMS messages as well the ability to cycle subscribers through the same email series.

True “Pro-Level” Features

This is the email marketing tool for those who want to create a self-running revenue engine that connects their website, email, and sales pipeline.

Behavioral Site Tracking

This is its “secret sauce.” You can trigger an email based on exactly what a subscriber does on your WordPress site.

Predictive Sending (AI)

It doesn’t just send at a “scheduled time.” It analyzes when each individual person on your list typically opens their mail and holds the message until that exact window.

The CRM Integration

It has a built-in sales pipeline. You can move “Deals” through stages (e.g., Lead → Review Sent → Follow-up → Closed) and have the email marketing adapt automatically based on the deal stage.

Split Automations

Most tools let you A/B test a subject line. ActiveCampaign lets you A/B test an entire workflow. You can send 50% of your leads down “Path A” and 50% down “Path B” to see which sequence generates more revenue.

Sender – Best free plan with automations

A free plan with automations? Yep. Sender is now the free plan king if you’re looking for email marketing and not just a weekly newsletter.

Incredibly generous free plan

Their free plan allows you to store up to 2,500 subscribers and send 15,000 emails per month. This is roughly five times the capacity of Mailer Lite’s free plan (they used to be the best free plan), giving a new business much more “runway” to grow before needing to pay for a subscription.

Unlike many other “budget” tools that lock their best features behind a paywall, Sender includes unlimited automation workflows, 24/7 live support, and access to their full library of 1,600+ responsive templates on the free plan.

Pro features for free?!

You can easily set up automated Welcome Sequences, Abandoned Cart reminders, and Re-engagement flows using a visual builder. It also acts as a basic CRM, allowing you to segment your audience based on their behavior (like what links they click) or custom tags.

It even includes transactional email capabilities (API/SMTP), meaning you can use it to send system-critical messages like order receipts and password resets alongside your marketing newsletters.

Pros and Cons

Brevo – Low frequency, high volume

Most platforms, as your list grows, your monthly bill goes up, even if you don’t email them. Brevo flips this on it’s head. You pay a low cost subscription fee and get an allowance of emails to send out each month.

100,000 emails for only $60 a month – What?!

That’s right, you can store up to 100,000 on the “starter” plan and pay only $60 or so to email your entire list. Brevo is the best choice for the ‘Low-Frequency, High-Volume’ email marketer.

If you have a huge list but you only send a monthly update or a few big launch sequences a year, why pay a subscription every month? Use Brevo to store a massive list that you intend on contacting once or twice a month.

Starter vs standard plan

Go with STARTER if:

Go with STANDARD if:

The Starter plan is for those who just want to email a big list periodically.

The Standard plan is for those who want more traditional email marketing features with Brevo workflows (their terminology for automations) along with AI send time optimizations.

Pros and Cons

Beehiiv – The newsletter platform

I have a very popular Beehiiv tutorial you can checkout. I’ve used Beehiiv extensively and it’s a powerful email newsletter platform focused on growth and monetization.

The platform’s core strength lies in its native growth loops, specifically the recommendation network and Boosts. When a new reader joins your list, Beehiiv can immediately show them a “Top 4” list of other newsletters you recommend, and those creators can return the favor, often leading to a viral growth effect that is hard to replicate on traditional ESPs.

Boosting with Beehiiv

For those with a budget, the Boosts marketplace allows you to pay for new, verified subscribers on a CPA (cost-per-acquisition) basis, or conversely, earn money by recommending other newsletters to your own growing audience.

Built in ad network

Monetization on Beehiiv is aggressive and built-in, featuring a native Ad Network that connects you with sponsors once you reach a certain scale. Unlike Substack, which takes a 10% cut of your earnings, beehiiv maintains a 0% platform fee on paid subscriptions, meaning you keep all your revenue aside from standard Stripe processing fees.

While you can run your own sponsorships like Justin Welsh does, it’s a bit time consuming and manual. Having to go back and forth with potential advertisers, negotiate a price point, have a timeline of when what ad is going to be published when.

With Beehiiv, it’s a simple, easy to use network that’s built in. You get a notification that a company want’s to run a display ad in your email and you simply approve or deny it.

Pros and Cons

Klaviyo – The “Industry Standard” for e-commerce.

Klaviyo is the gold standard if you’re running a profitable e-commerce website. It is incredibly powerful, but also complex and expensive. For a beginner, Klaviyo is like being handed the keys to a Ferrari when you’ve only just learned to drive; it’s fast and impressive, but it’s very easy to feel overwhelmed.

The “Shopify Specialist”

Klaviyo’s biggest claim to fame is its “creepy good” integration with Shopify. It doesn’t just see your customers; it tracks every move they make. It knows exactly when a customer looks at a specific blue shirt, adds it to their cart, and then leaves.

Because of this, its “Abandoned Cart” and “Browse Abandonment” flows are the most effective in the business, often paying for the software’s high cost through recovered sales alone.

Advanced Intelligence & Data

Klaviyo (like most companies) has leaned heavily into AI and Predictive Analytics. It can actually predict a customer’s “Next Purchase Date” or their “Churn Risk” (the likelihood they’ll never buy again) based on years of data patterns.

It also combines Email and SMS into one single timeline, so you can see exactly how a customer interacts with your brand across every channel without having to jump between different apps.

Pros & Cons

Flodesk – The “Aesthetics First” option

While tools like Klaviyo focus on data and Brevo focuses on cost-efficiency, Flodesk is built for creators where the look of the email is the most important part of the brand.

It is the best choice for designers, photographers, or lifestyle influencers who want their emails to look like high-end digital magazines without touching a single line of CSS.

Flodesk’s main differentiator is its proprietary layout engine. Unlike standard editors that can be clunky, Flodesk allows you to overlap images, use custom fonts that actually show up in the inbox, and create pixel-perfect spacing.

It is essentially “Canva for Email,” making it almost impossible to send a basic looking email.

Workflows that work

For a beginner, the power of Flodesk workflows lies in “Link Actions” and “Behavioral Conditions.” You can set up a system where, if a subscriber clicks a specific link in your email (like a “Video Review” link), Flodesk automatically tags them or moves them into a new “Hot Lead” workflow without you lifting a finger.

It also handles the “logic of time” exceptionally well, letting you schedule delays down to the specific minute, day of the week, or even a specific time of day, ensuring your “Welcome Sequence” always hits their inbox exactly when they are most likely to be active.

Basic but useful ecommerce features

Flodesk does have a native Abandoned Cart and Post-Purchase workflows. If you connect your shop (Shopify, WooCommerce, or even Flodesk’s own “Checkouts”), you can trigger automated nudges the moment someone leaves an item in their cart or send a specific guide or upsell immediately after they buy.
