This post will discuss the 5 most common email marketing errors that beginners make and how you can overcome them.

Error 1: Not paying attention to Welcome Email.

The first thing you see is your welcome email. However, most novices omit it or write a perfunctory thanks you subscribed note that is one-dimensional.

Why It's a Mistake:

  1. Subscribers want a friendly demeanor of introduction.

  2. Its absence, the interest wanes fast.

  3. You lose the opportunity to define expectations.

How to Avoid It:

  1. Send a personal welcome email as soon as you sign up.

  2. Tell your story, what you are trying to do and what should be expected by subscribers.

  3. Add a little "fast cash" such as a free course guide, tip or discount.

Pro Tip: A well written welcome email is likely to be the email that gets the highest open rate of any email you will send.

Error 2: Sending Un-segmented Emails.

A lot of amateurs send out the same email to the whole list. However, not all of your subscribers are identical and treating them so is a quick way to lose subscribers.

Why It's a Mistake:

  1. Generic messages are irrelevant.

  2. Engagement rates plummet.

  3. Large unsubscribe rates/spam complaints are harmful to deliverability.

How to Avoid It:

  1. Go small: divide into interest, location, or behavior.

  2. Example: Email different people who are customers vs. customers who are leads.

  3. Add labels to categorize the subscribers according to what they have clicked or bought.

  4. Open and click rates may increase by 14 and 100 percent respectively even with simple segmentation.

Error 3: Lighting up Sales Pitches.

We get it you want sales. However, when all the emails are Buy Now messages, your list will go dead pretty quickly.

Why It's a Mistake:

  1. Feels pushy and spammy.

  2. Win the confidence of your subscribers.

  3. Causes a higher number of unsubscribes than conversions.

How to Avoid It:

  1. Uphold the 80/20 principle: 80 percent value, 20 percent promotion.

  2. Give tips, instructions, or problem solving stories.

  3. Sell emails should not be needy but should be in a conversational tone.

  4. Consider your emails a relationship. People do not like to hear you talking about yourself.

Error 4: Mobile Optimization is not done.

Over 60 percent of emails are opened through handheld devices. However, most novices create emails that appear fabulous on a desktop computer and fail on a mobile phone.

Why It's a Mistake:

  1. Unreadable emails are caused by bad formatting.

  2. There can be links and buttons too small to tap.

  3. Your emails are instantly abandoned.

How to Avoid It:

  1. Make use of mobile-responsive templates.

  2. Make subject lines short (less than 40 characters).

  3. Find huge buttons that can be tapped (not tiny links).

  4. Check your emails on mobile and desktop prior to sending them.

Unless it looks good on your phone, it will not work with many of your subscribers either.

Error 5: Failure to track or test performance.

Most amateurs put it in and leave it. They mail e-mails, but never bother to check what works and worst of all, they are left to guess.

Why It's a Mistake:

  1. What is driving results you do not know.

  2. Recurrence of the same mistakes is economically inefficient.

  3. Lack of chance to enhance conversions.

How to Avoid It:

  1. Monitor the essential indicators: open rate, click-through rate, unsubscribe rate, conversions.

  2. Carry out basic A/B tests (subject lines, send time, CTA buttons, etc.).

  3. Learn and improve the future campaigns.

Even minor changes such as a subject line may boost the open rate by as much as 20%.
