Email Open Rates to increase with these 4 tips

Email open rates make or break your sale

If you connect with your customers by email, you’ll need magnetic Subject Line to attract them to open your email.

Just 4 quick no-nos to avoid and your email open rates will improve.

No more guessing game nor wet finger in the air (crude and unhygienic way for checking wind direction).

Follow these tips and you should be fine.

(Based on the believe that you have great product and service and an irresistible offer.)



1. Following the same style since day one.

With tonnes of emails daily, how many boring looking Subject Line do you actually click on?

A dull, same ‘ol Subject Line is not your friend in the Open-Rate party.

Be unpredictable, all the time.


This is totally opposite from the tip for From Line. From Line has to be consistent for trust and comfort.

Subject line however, requires you to be as creative as you can.

This is the only time you are rewarded with higher email open rates for going against the traffic.

Unpredictability improves readership and ultimately sales.



2. Go ahead, add on all the bells and whistles in the Subject Line

Whatever is not necessary, please, remove it.

Let the Subject Line be as focused as possible, quick to understand without the fluff.

I know it’s tempting to squeeze in as many stuff as you can in the Subject Line because you can and because your boss wants you to really show off the company’s best and because your product manager is overly excited about the cool features and benefits.

See? No one likes to read long sentences, let alone the Subject Line.


Subject Line is like the headline on the newspapers or advertisement.

The shorter and more precise it is, the more people will read.

Trim and prune it well for good email open rates.

Which brings us to the next point…



3. Must add in brand, product name and date of launch.

Your branding, usually your name, should only be at the From Line.

That’s where your readers recognise you.

Neither do we put the product name, because it’ll look like unsolicited mass email.

Try to state the benefits instead.

Or even better, user’s response from the benefits.

Brand, product and date of lunch spell boring.


Instead of:

Haze, no more a concern at home



4. Long Subject Line looks ok on Desktop

Not from this year onwards.

According to MarketingSherpa, email open rates for desktop is 32.97%.

For mobile, it has overtaken desktop at a whooping 50.12%

It means more people are opening their email on their mobile.

That also means mobile readers only get to see limited words being displayed in the preview window.


Our job is to make it as easy as possible for the readers to decide opening your mail.

I’ve been studying advertising headlines and found that attractive headlines have less than 5-6 words.

To make sure your Subject Line does not get truncated, aim to write your Subject Line within 30 characters.

40 is too much.


Keep it short for sweet email open rates


Bonus! Top 100 words to avoid in a Subject Line

I found this site while I was doing some research on this topic.

It has the top 100 words to avoid in the email Subject Line.

According to the article:

Most ISPs and email clients use various filters to scan incoming email to determine if they should be delivered to the Inbox or Spam folder. The spam filters check for spam triggering words in the subject line and email content based on their weightage.


Hope it’ll be handy to you.
