In other words, the main goal of Convertkit is to help your business draw more potential audience and turn your new subscriber into a paying customer.

Standard Essential Terms Used in Convertkit

Understanding the aspects of Convertkit can be challenging, especially for beginners.

As such, here are some essential terms that you should keep in mind when talking about Convertkit:

  • Form: Convertkit form is where your potential subscribers will provide their details such as email address, name, and location.
  • Landing Page: This page aims at increasing conversion rates. It is a dedicated page that contains your content and form. You can also design this page to enhance the results.
  • Sequence: It refers to a sequence of emails sent to a new subscriber. 
  • Broadcast: It refers to a scheduled email sent to a particular segment of your subscribers or a large group of contacts at once.
  • Tag: Convertkit tag helps you track your subscribers’ interactions with your content. You can use this feature to identify the subscribers’ interests based on what they do.

What is the Purpose of Convertkit?

But what can you do with Convertkit?

The following are some essential things you get to enjoy by becoming a Convertkit subscriber:

You can:

  • Put sign-up forms on your blog post.
  • Provide an email course to your subscribers.
  • Give a bonus for new subscribers.
  • Offer giveaways for subscribers.
  • Send exclusive content to those who sign-up.

Why is Convertkit better than MailChimp?

List Management

One of the reasons why Convertkit is better than Mailchimp relates to how they handle your email list. Mailchimp is a list-based email autoresponder.

It means that you will have to create individual lists to segment different people.

With Convertkit, you will have a master list where you can add form, sequence, and tag to a contact.

The advantage of this aspect is that it is extremely easy to stay organized with your subscribers.


Automation is another feature that makes Convertkit stands out from Mailchimp.

With Convertkit, you can send personalized emails to each subscriber on your list based on their past actions.

Additionally, as you build the sequence, you can also create and edit the emails without moving to another section or page.

Visual automation is the best attribute of Convertkit that allows you to define how an individual should enter a sequence.

Moreover, you can see a graphical representation of how to add or remove tags and when people are buying something.

But with Mailchimp, you will need to use a paper or other programs to complete these tasks.

The reason is that Mailchimp does not have visual representation like you get with Convertkit.

Unrivaled Customer Service

Another essential feature that makes Convertkit better than Mailchimp comes with customer service.

Unlike Mailchimp, Convertkit provides support to its customers in the form of live chat and email. Additionally, it offers support documentation and video tutorials.

As such, if you find it challenging to understand the documentation, you can always use the live chat support.

Quick note: If you find that ConvertKit is expensive you can try the below alternatives email marketing services:

  • Aweber
  • MailerLite
  • SendPulse
  • Benchmark
  • Drip
  • GetResponse
  • OptinMonster

In my opinion, ConvertKit has the best platform for automating email deliverability and increasing conversion rate.

But If you still don’t think the email marketing service is right for you, then there are many other ConvertKit alternatives to consider too.

Lets look at how to fix the 10 common Convertkit errors.

1. Fixing Formatting Issues

It is uncommon for users to experience text problems in their emails. If you are wondering why the font size changes without any apparent reason, we are here to help you. 

When it comes to formatting issues in email, the most common problem that many users face relates to inconsistent text size.

Sometimes, some text can appear smaller than the remaining passage, as shown in the image below.

You should note that most of the formatting issues result from copy-pasting your content from external sources.

The reason is that you are not merely copying the text but also the text’s style.

As shown in the above image, the first line appears smaller than the rest of the text. If such formatting issues occur, then you should follow the steps to fix the problem.

Firstly, you should select the text that requires change, as shown below:

Next, you should click on the formatting icon where you can set the selected line to normal text.

We have included another image for your reference below:

Sometimes, the above step might not fix the formatting issue. If it does not work, then do not panic. We have another solution for you.

You should first click on the font size icon, and then you can set the text size to default. For instance:

Now, you should have fixed the text formatting issue.

However, if the above steps do not solve the problem, we recommend deleting the text and re-typing it again.

2. Attaching an Incentive

The incentive email, also known as a confirmation email, is essential as it creates your first impression to your new subscribers.

This email gets sent-out to subscribers as soon as they subscribe to your form or your landing page.

You can have the incentive email act as a basic confirmation email or add a download file.

Once you have created a new form and attached an incentive file, your subscribers should be able to download the uploaded file.

Sometimes, your subscribers can experience trouble.

Here is what you can do.

First, you should verify that you have uploaded the file to your form successfully.

To check this issue, you should click the email icon on the right toolbar, which will show the incentive email.

On this page, you should ensure that you have selected the download and not the URL.

Additionally, you should make sure that your filename is present at the bottom of the page. The below image is how your incentive email page should look.

3. Attaching PDF to a Landing Page

This aspect is another issue that you are most like to experience when using Convertkit.

Typically, an error message appears when you try downloading your uploaded incentive file attached to your landing page. We have included the error message below:

You can fix this issue by following the following steps:

One of the ways to solve this issue is by re-saving or re-uploading the file.

You need to re-upload the PDF on the incentive email page if it is a duplicate form, made from an original working form.

Another way is by making changes to the filename.

You should make sure that your PDF filename does not contain any special character, and it should be less than 20 characters.

Besides, the filename should not contain any spaces or underscores.

4. A Fatal Error

This error happens when you try to delete subscribers from your list on an individual basis.

One way of fixing this issue is by deleting multiple subscribers at once through bulk action.

You can manually unsubscribe your subscribers by clicking on the “Unsubscribe” button on the left sidebar.

In this way, you can maintain your subscriber history and re-activate them if they request it.

However, if these do not fix the issue, then we recommend seeking support at   

5. Personalizing Confirmation Email

You should note that it is impossible to personalize the confirmation email sent by Convertkit to your new subscribers.

The only solution to this issue is to set up an automated email sequence that will instantly send out when someone subscribes to your list.

However, if you are using the free plan, you cannot access this feature in Convertkit.

First, you should go to the sequences and then click the new sequence, as shown below.

By clicking on the new sequence, Convertkit will direct you to name your sequence. Remember, your subscribers cannot see this name.

Once you have created the name for your sequence, you should click the create sequence button.

Once you have created a new sequence and written an introductory email, you should set the timing to zero by clicking on the “When to Send.”

This way, your personalized welcome email gets delivered immediately along with the Convertkit confirmation after your subscriber signs up.

6. Forms Disappearing

One way of fixing this issue is by refreshing your forms.

First, you should go to your WordPress dashboard, and then navigate through plugins—Convertkit—settings.

Next, you should click on the “Refresh Forms” button.

Another way is by resetting your API connection. First, you should click on the plugins by going to your WordPress dashboard.

Next, you should click on the Convertkit, and then on the settings. Now all you have to do is to remove the text in the API key and API secret.

Finally, you should click on the save changes button.

7. Limitations on Free Trial

When it comes to Convertkit free and paid versions, there is no difference in the features of form and text front styling.

In comparison, the styling forms in Convertkit have improved a lot.

However, when it comes to changing fonts, you will have to use Cascading Style Sheets (CSS).

8. Customizing Confirmation Email

To fix this issue, go to the incentive email and click on the envelope icon.

You can then click on the “Edit Email Contents,” as shown below:

Finally, you can select the sending email address, change the subject line, and email content.

Including a link to your broadcast allows your subscribers to read your content. It also provides the ability to share it with their friends.

To include a web link to your broadcasts, you should first highlight the text as shown below:

Next, you should click the link icon and add the “archive url.” Once you have sent the broadcast, it will link to the public archive page.

10. Unable to Complete MailChimp Migration

First, you should choose those lists that you want to migrate from the Mailchimp.

Next, you should the “Export” button to start the process, as shown below:

However, you should export each list individually.

The next step is to create a tag in Convertkit, which you can achieve by clicking on the “+ Create Tag.” Additionally, provide a tag name.

Next, you should click the “Add Subscribers” and then click on the import a CSV.

The final step is to fill the “Import Subscribers” page. You should repeat these steps for each list in your Mailchimp.
