10 Best Free Email Subject Line Generators (in 2021)
What is the first thing that a recipient notices upon receiving an email? It is the subject line of the email.
If the subject line is not impressive, why would the recipient even care to open the email?
According to a study, 33% of recipients open their emails just by looking at the subject line.
This is one chief reason why the subject lines used in email campaigns have to be striking. They are as important as the message inside, and you must work on them.
The first instinct of the recipient upon seeing the subject line should be to click open the email, and you should do something for that. It has to draw the attention of the reader or else it is very easy for the email to blend with the hundreds of others in the inbox.
That is what we are going to talk about here: the best email subject line generators that will give you subject lines with high open rates.
Tips for Writing Cold Email Subject Lines
What should you put in the subject line of a cold email to make it stand out from the crowd?
Here’s how you can come up with impressive email subject lines:
They should be short
Keeping subject lines short and sweet will help catch the attention of the recipient.
If you choose to use long subject lines, they will get trimmed off in the inbox making your efforts seem futile. It is crucial because a lot of people read their emails on mobile devices. You wouldn’t want to miss out on that audience.
So, keep the length in mind while working on subject lines.
They should have a sense of urgency
When you create a sense of urgency in the subject line, the open rate is higher. This is a good tactic, but you must not over-use it.
Reserve such subject lines for new, time-bound deals to lure the recipient into opening the email.
Keep a recognizable sender name
Nobody would like to read a message from a robot. Messages from firstname.lastname@example.org most often go unread and end up in the trash folder.
So, you have to keep it more human-like.
Set the sender name in such a way that it looks as though a human has sent it. You can choose to use your company’s team member’s name to bring a personal touch to it. These little things add up and matter a lot when it comes to an email campaign.
By getting personal with the recipient, you make them feel that they are essential.
Recipients would give a more robust reaction when they look at their name in the subject line. Such emails have a higher open rate than the ones without the recipient’s first name.
Find out the prospects’ interests and make them feel that the email has something in it to which they can relate. Mentioning that using very few words is an art in the subject line, but if you manage to learn it, you will be in profit.
