Simple Opt In Form Hack That Increase Email Subscribers

Simple Opt In Form Hack That Increase Email Subscribers

Is your opt in form sleeping on the job? Even with so many awesome opt in form platforms and designs, it’s still hard to customize and optimize these opt in forms in a way that assures that you grab your ideal customers’ attention.

Usually, we spend a ton of time on our offers or our landing page designs. And there’s nothing wrong with that.

But, did you know that you can increase email subscribers by just tweaking your opt-in form? In this article, I’m going to share four ways that you can make right now to increase the number of opt-ins you get.

I get so many questions about what type of opt in form to use or what the best colors are for buttons. So I thought I’d answer them right here.

What fields to include in an opt in form

The highest converting opt in forms have two fields; name and email. The conversion rate of a form will drop by 20% for every form field that you add.

Think carefully about adding a phone number- because that field alone decreased opt ins by 48%. I would recommend that you only add a “phone” field if there is a good reason to contact the person such as confirming an appointment or sending a text reminder if they want to receive it.

If you have to ask for more info beyond the two form fields, include the word “Optional” in parentheses next to the extra form fields.

Simply adding “optional” in the field can increase the conversion rate of forms using more than two form fields.

How to label opt in fields to increase conversions

Another way to boost email opt-in conversions is to specify the call to action (what you want people to do) as part of the field.

For example, where you want people to enter their email. Give them the direction “Enter your email here” either inside the field or next to the field.

What’s the best call to action button color to use?

Historically, these are the most effective call to action button colors to use:

You don’t have to take these colors literally, use a variation that works with your brand colors.

If your business targets primarily women or men, you can adjust your button colors based on the primary preferences for men or women.

Joe Hallock studied the color preferences of men and women to help marketers figure out what colors to use on their buttons to appeal to certain audiences.

The top three color preferences by women are blue at 35%. Purple at 23%. And green at 14%. For men, the top three colors were blue at 57% green at 14% and black at 9%.

What opt in button text converts the best?

Now that you have the button colors ironed out, let’s look at what text to use inside the button that will increase your conversion rate.

Research shows that you should use 3-4 words inside the button text. Another tips is to make that text a command in the first person:
