We’ll never increase pricing because your email list is growing

What is email automation?

Email automation lets you create emails that get sent automatically at the exact second they’re needed, without you clicking send every time. You create the email, you define what needs to happen for it to be sent, and your email marketing tool does the rest.

For example, imagine you just signed up for a mailing list or bought something online; what’s the first thing you expect?

An email confirmation, right?

If you don’t receive it, you’ll probably start to get antsy. Maybe you’ll start worrying that something went wrong, or even that you might have been scammed.

This little story paints a picture of what email automation is and why it’s so important. Those welcome emails or order confirmations are examples of email automation in action.

There is almost no limit to the automated emails you can create. Most businesses automate a welcome email for their new subscribers, but you can get incredibly granular with how you target people and what events trigger an automated email from your brand—especially when you connect your website analytics tools to your chosen marketing automation tool. 

In order to pick the best tools for the job, you need to know what you’ll be doing with them. So, let’s take a quick look at the typical features and terms involved in email automation.

User segmentation

Audience segmentation involves categorizing your subscriber lists based on their commonalities so you can send the most relevant message to every contact. These categories are usually based on demographics (gender, age, location, ethnicity, etc) or psychographics (past behavior, beliefs, hobbies, personalities, etc).

Audience segments are how you show your subscribers that you understand them and are deeply relevant to their lives. Perhaps you have a segment of contacts who identify as leaders and another for creatives, or one for introverts and another for extroverts.

Any email marketing tool worth its salt gives you the ability to categorize your subscribers into these “segments.” It’s an incredibly powerful way to get your automated emails to deliver maximum value to every subscriber on your lists.

Automated workflows

Email workflows are the instructions you create within your email marketing tool to send automatic emails based on your subscribers’ preferences and user segments. Often, marketers create a series of these emails that work together to achieve goals like onboarding new users or enhancing the purchasing journey.

Workflows are the cornerstone of email automation. Also known as email nurture streams, they allow you to send the right message to the right people at the right time. They are endlessly versatile and fully customizable to your needs.

One of the most common Flodesk workflows we help with is automatically sharing a free download with your subscribers. Other common examples include (but are not limited to):

  • Emails for upcoming birthdays or anniversaries (typically including some kind of celebratory discount for those using email software for ecommerce).
  • Welcome emails to greet new subscribers.
  • Follow-up emails for contacts who abandoned their shopping cart or visited a specific page of your website.


Integrations connect your email marketing tool to the other systems and software that you use. This is how you tie your email marketing platform to everything from your website to your ecommerce platform or your CRM system.

Many top email service providers include direct integrations with such industry giants as WordPress, Shopify or Salesforce. It’s also common to find hundreds more integration options via Zapier, which acts as an easy-to-use intermediary connector.

For the more tech-savvy among you, some providers include open APIs, which allow you to build your own bespoke integrations if you can’t find the existing integration that you need.


Think of triggers as a catalyst for action. They’re what tells your marketing software to send out a particular email. The trigger effectively says, “Hey Flodesk, X person just took Y action. Send them the email for Y action.”

Triggers can be everything from a subscriber’s activity to a specific date or event. You get to choose what your triggers are and what messages are sent out when a trigger condition is met.

Here are some examples of automated emails:

  • Trigger: Someone subscribes to your mailing list.
  • Email: “Welcome!”
  • Trigger: A subscriber’s one-year sign-up anniversary.
  • Email: “Happy anniversary! We have a gift for you.”
  • Trigger: Someone leaves your site with unpurchased items in their basket.
  • Email: “We’re holding those items for you.”

With machine learning, predictive tools, high email deliverability rates and an army of fans, this top-tier software is an ideal fit for anyone looking to dive in at the deep end, so to speak.

A fan favorite among B2C ecommerce brands, Klaviyo is one of the best email automation providers for anyone in the retail business. If you’re set up and selling via Shopify, you’ll find this software particularly suited to your needs.

While Klaviyo has many fans for this reason alone, if you’re not running a retail ecommerce store, we recommend looking elsewhere for your email automation needs.


  • Excellent pre-built automation workflows, particularly those focused on maximizing sales opportunities based on user behavior.
  • Highly customizable audience segmentation features, adaptable to respond to a rich assortment of rules.

Klaviyo offers a free plan for anyone who has fewer than 250 subscribers and sends fewer than 500 monthly emails.

If that’s not you, then you’ll need a paid plan. As with most email service providers, Klaviyo charges you based on how many contacts you have and how many emails you need to send. 

Here’s how their prices get started:

Best email marketing automation software for online creators such as bloggers or course creators.

As an email marketing software built by online creators, for online creators, ConvertKit comes packed with some powerful automation features designed to have you converting subscribers in record time.

The visual automation of ConvertKit is especially attractive and cuts out the complexity prevalent in other email service provider workflows. Careful though, their plan pricing can quickly get out of hand.

  • Simple to complex automation rules let you create a variety of customer funnels.

  • A free plan.


  • Cost is higher than it should be and can quickly burn a hole in your profit margins, particularly if you manage multiple clients and/or large email lists.
  • Tricky interface with quite a steep learning curve at times.
  • A rigid focus on online creators, which limits the usefulness of ConvertKit for other users.
  • The lack of lead importing features means you’ll need to manually add your contacts.
  • The email template editor is pretty basic—you won’t be able to create the same beautiful emails as you can through alternatives like Flodesk unless you have basic coding skills.


ConvertKit offers a free plan that allows for up to 300 subscribers and gives you access to unlimited emails, forms and landing pages.

Beyond that, they keep things simple with two plans, Creator and Creator Pro, which each get more expensive the more subscribers you have. They also only withhold a few features for their top-tier Pro plan, which is a nice touch.

You can expect to find the usual automation tools within Mailchimp’s software: everything from simple autoresponders to more advanced campaigns driven by customized triggers like audience behavior. Because Mailchimp is something of an email marketing Swiss Army knife, it’s not laser-focused on automation specifically—but as long as you’re on one of the paid plans, you’ll get on just fine.
