If you are looking for proven methods to improve your email marketing’s performance this list of resources shows you what can be done and how.

1. Personalization

Using this tactic is a great way to improve the performance of your email. A study made by Experian has found that emails with personalized subject lines are 26% more likely to be opened than those without. Another study, this time by Rich Relevance found that revenue is 5.7 times higher in emails that employ personalization.

The most common personalization tactic is to use your recipient’s name in the email subject line. A study by the Stanford Graduate School of Business found that by simply adding the name to the subject line of an email, it has the ability to increase the probability of an open by 20%, boost sales leads by 31% and reduce unsubscription rates by 17%. Pretty awesome, right?

2. Segmentation

A study by Campaign Monitor found that marketers who use segmented campaigns see as much as a 760% increase in revenue. 

What is it? Segmentation means dividing your audience into smaller groups based on characteristics they have in common which you can decide based on activity, surveys, and stage of their customer jouney.

Through this practice you can tailor (or personalize) your marketing to address specific customers with relevant offers and language.

It is commonly used by brands that sell multiple products to different audiences.

You can create segments that group email subscribers by product usage, demographics, psychographics, buyer’s journey, engagement with your brand (new vs returning), desktop vs. mobile.

Segmentation can happen as soon as you have a new contact in your CRM. You can do it via a survey, the sign up form or a link within the welcome email.

If you have a clear customer journey for each segment, then you can use automations to educate, nurture and convert (read down the page).

4. Customer journeys

When you know your customer and you have a well planned content and offer calendar for at least three to six months, you will be able to reap the benefits of automation or customr journeys.

This is a series of automated emails that get triggered by specific actions an email subscriber or customer performs within your email campaigns, other automations, or interaction with your website.

Example of triggers: signing up for a mailing list, purchasing or not purchasing a specific product, clicking on a specific link in your recent campaign (newsletter), staying on your list for a specific time but not purchasing or not opening your emails, visiting specific pages, signing up for a webinar, lead magnet etc.

Example of automations: welcome sequence, abandoned cart, indoctrination, soap opera, promotion etc.
