“I don't want no scrub, a scrub is an email that can't get no love from me.”

Here at Campaign Nucleus, we want to make it as easy as possible for our users to produce the most successful email content possible. With that our team has done some research and put together some information we’ve found helpful in creating our own emails.

Let’s start simple – what are the things that every recipient is going to notice about your email?

1. Your sender
2. Your subject line
3. Your content

Now let’s talk about how we can utilize all 3 of these factors to create the MOST TOP NOTCH EMAIL possible!!

Sender:

When you see an email in your inbox, what is the first thing you see? Likely, the sender’s name. Are you more likely to open an email that appears to be sent from a specific person or one that declares a corporation. Likely, a specific name.

Well, your audience feels the same. This means you can improve your user engagement simply by using a more personalized sender, such as a team member, to make your communications seem more “human”and less “AI generated.”

For example, an email being sent from Julia from Nucleus may perform a bit better than one being sent from the Biden Administration (although that may have more than one reason for performing poorly…).\

With that, consistency is also always key – it’s a good habit to keep one sender and domain affiliated with each type of content being sent.

Subject Line:

Following the sender, you likely immediately notice the subject line affiliated with the email.

When it comes to subject line, there are a couple things to keep in mind:

• Topic – always make sure your subject line sticks to the point. No one wants to open an email that has nothing to do with the subject line… it appears deceiving

• Length – your subject line length can actually drive your engagement. Short subject lines (below 50 characters) & longer subject lines (above 70 characters) actually have been found to receive more engagement than average-length subject lines.
  

Content:

The last thing the recipient will see but generally the most important portion of the email for them to see.

There are lots of considerations to be made when designing our content & every audience type responds differently to different copy types.

We encourage individuality in your sends but here are a few things to keep in mind:

• Be concise – the average human has a reading attention span that ranges from 10-15 seconds… that isn’t very long.

• Consider your call to action – it’s good practice to include multiple links within the email & our system makes it easy to determine where your audience is engaging the most within your email.
  

• Always check variables – we want to make sure we do not address our recipients as “Hello %recipient.first%.”

• Make your email readable – this includes but is not limited to:
  • Having a nice layout – easy to read & pictures should never outweigh text
  • Using color and branding wisely
  • Ensuring pictures are high enough quality that they engage your audience (although too much data can slow your email load time & that isn’t great either)
