Why Is Email Marketing Important?

You might be thinking - social media and digital advertisements are the life and death of email, so who needs email?

A few facts on email marketing:

  • More than 4 billion people worldwide use email. That’s big audience and opportunities for your brand.
  • Email converts 3 times as much as social media. People glued to email are hot leads.
  • 61% of customers would like to get promotional emails, sometimes, if the brands are companies they do business with. They expect it.

As you may have seen, email isn’t going anywhere. Taking the time to update and improve your email campaign will pay so much in your bottom line.

Here’s how:

Step 1 - Build Your Email List

You will not receive the email you worked so hard to build if you don’t have an email list for your first marketing campaign. Lists: Your list is your most valuable resource as a marketer.

There are many ways to expand your email list:

  • Offer a lead magnet - A deal, a free eBook, checklist or anything you would like in return for an email. Guarantee it has some actual value.
  • Social Media contests - Create Facebook contests and make signing up an email address necessary to participate. Great way to get to know your new subscribers.
  • CTA’s on website - Provide opt-in email boxes and CTA’s on your website pages and blog. Give them something in return - a discount code or something.
  • Go Beyond Online - Place a signup form or call to action on everything print (business cards, flyers, etc). Showcase your signup form at events.
  • Retargeting ads - Display ads used for site visitors and subscription requesting.
  • Email Forwarding - Ask your subscribers to forward your emails to friends so that you could build your list through referrals.

Email marketing is extremely powerful the larger your list, the stronger it becomes. Build a good list not a big list and look at your list as gold. Treat it well and you will have it for years to come.

Step 2 - Segment Your List

Once you have an email subscriber list, you group or segment it according to: demographic, interest and even behavior data of users.

This means you only send the best, relevant emails. Your sections might be something like: For instance, your sections might be:

  • Recent customers
  • Cart abandoners
  • Loyalty program members
  • First-time buyers
  • Engaged subscribers

Splitting is more work, but big payoffs. Here’s why:

  • Increase open & click through rates - Optimized emails have very high open and click-through rates which means more sales.
  • Personalize - Provide segmented groups with personalized content based on what they are interested in and require. Builds your connection.
  • Conversion - Send all group email campaigns/offers designed especially for them to help conversions.
  • Convert campaigns better - Find which audiences are most responsive to which campaigns. Refine your approach.
  • Automation campaigns - create segments that send out automated email campaigns. You can for example create cart abandonment emails for those users who abandoned their cart online.

Spend some time separating your subscribers accordingly. It can also do wonders to your email performance.

Step 3 - Optimize Your Email Design

If you’re going to actually get people to read your emails and give them a chance, then your design and content must be smart, simple, even scannable.

Guidelines on Email Design Best Practices:

  • Mobile optimized - Over half of emails get opened on mobile. Use a responsive design.
  • Pronounce subject line - First impression is everything so a descriptive yet interesting subject line should do the trick. Chasing curiosity rather than clickbait.
  • Images and Similar Images - By adding them the content will look better and stay in user’s mind. Photos have to be sent in email optimised.
  • Short Paragraphs - We know that writing in an easy to understand format brings in more people. Avoid big blocks of text.
  • Powerful CTA’s - Tell readers what to do next, such as to join, shop the sale, RSVP, etc. Color-Code CTAs.
  • Fonts that are readable - Choose the minimal, simple, and legible fonts. Scribble big and short ornaments and large text.
  • Extra generous white space - White space is easier to read. Don't clutter the design.
  • Include consistent Logos, colors, fonts, images - But don’t overdo it - Content is always number one.

Invest a little time on nice looking email templates. It is going to improve results. Design some template and test.

Step 4 - Write Great Subject Lines

Your email will have a very short life due to the subject line. A bad subject line will take your email to the trash, a good one will bring open rates.

Here are a few principles to be a master subject line writer:

  • Deliver the Material Before it’s Time - Do not just announce "New Product Release!"
  • Ride the trends - Tap into whatever is around them such as holiday, tunin event or season.
  • Question - A question hooks the reader in from the start.
  • Call to action - Value or savings subject lines get higher open rates.
  • Solution problems - Solve customers’ problems, problems or demands.
  • Utilize Emotions - Subject lines that pique interest, passion or urgency go viral. But avoid overusing ALL CAPS.
  • Have a short mail - Keep it under 50 characters so the entire name appears on all devices.
  • Make sure you A/B test the subject line to find the one that really resonates. Refine over time.

Don’t forget - you only have 3-5 seconds to get recipients to open your email. Keep in mind that the subject line is your one big opportunity to snag (or lose) their interest.

Step 5 - Grow Your List with Lead Magnets

Lead magnets were one list building tool we’ve touched upon before. But what exactly are they?

A lead magnet or opt-in incentive is just something you provide for free in exchange for their email address (it could be any piece of content, product, or gift). This comes mainly in the form of:

  • EBooks
  • Whitepapers
  • Coupons
  • Checklists
  • Free trials
  • Webinars
  • Discounts
  • Giveaways

It’s because lead magnets are instant value to your prospects that they are effective. But no freebie will do.

Your lead magnet should:

  • Discover a customer pain point or need. Find their pain points.
  • Provide really useful information - not some content marketing hoax.
  • It needs to be pretty - now is your chance to attract subscribers.
  • This lead magnet is a way to start developing trust and authority.

Avoid basic cheap lead magnets like eBooks, brochures or infographics. Do some background research on your niche and competition to build a special lead magnet that your customers will love.

Last but not least, promote your lead magnet across your website, social and offline presence to scale your email list fast.

Step 6 - Automate and Streamline with Email Sequences

All that hard work to send single emails a few times! And that’s why every email marketer should make use of automated email sequences.

They’re also referred to as auto responders or email chains and they are series of prepared emails that get delivered automatically to subscribers once they perform (or don’t perform) certain actions.

Some common email sequences: Below are some sample sequences:

  • Welcome sequence - Offer subscribers helpful onboarding material to initiate the connection.
  • Cart abandonment - Remind people about items they have in their online cart that were not bought yet.
  • Browse abandonment - Reconnect with online users who looked around but never bought.
  • After-sale - Confirmation of purchase, shipping details, request for reviews, etc.
  • Win-back - Try to woo inactive email list back with a coupon.
  • Re-engagement - Send subscribers something new once they’ve gone months without any engagement.
  • Birthday - Reward subscriber birthdays and earn karma.

This will save you so much time as well as make your message memorable and relevant with the right email sequences. It only needs to be configured once, and the automation does the rest!

Step 7- Track and Measure Your Email Results.

Optimizing your email marketing is just one way to go crazy with it thanks to constant measurement.

Here are the Email Analytics you should care about:

  • Open rate - Number of subscribers for which your email was opened. That is between 20-25 % which is industry standard.
  • CTR (click-through rate) - Number of people that opened a link in the email. Benchmark is 2-5%.
  • Conversion rate - The percent who did something you asked for like spending money. Varies widely by industry.
  • Bounce rate - The percent of bounced email which did not get delivered. Aim for less than 5%.
  • Unsubscribe percentage - The number of people who have unsubscribed from your list. Keep below 0.2% if possible.
  • List Growth - How fast your email list is growing with new members. Faster growth is better.
  • Engagement - Beside opens and clicks, also measure other types of engagement like general social shares, downloads, post-click conversions, etc.
  • Email client/device statistics - View important information like which email clients/devices are the best or worst.
  • Email scheduler - Try sending on different days of the week and times of day to maximize open rates.
  • Email subject line A/B testing - A/B test email subject lines to see which one opens the most.
  • Email copy test - Test whole email content (e.g., long copy vs short copy).

Track every single stat, A/B test, report your results and optimise your campaigns. Even a 1%, 2% or 3% up on any given measure adds up.

Final Thoughts

Email is all about real content, quality subscriber relationships, messaging that matters. Be on top of email best practices like we have mentioned here, track your outcomes, and keep tweaking your campaigns.

And if done right, email marketing will soon be one of your most successful and successful marketing avenues. All you have to remember - quantity not quality and relevancy is the name of the game. Build that relationship of trust with your list and it will pay off.
