how to make a good email marketing subject line?

Creating a good subject line is a fundamental step in any email marketing strategy, but getting one that captures the attention of users is not as easy as it seems. Today we give you the best tips to reach your subscribers effectively.

15 steps to follow to get the best subject line in email marketing

1. clearly mention what the email is about. To write a good subject line, the first thing to do is to specify the subject you are going to address, and you have to do it in a short sentence. The subject line of an email is like the headline of a news item, so it must meet the same requirements to be effective.
   
   
2. use the surprise factor. Email subject lines do not have to be totally descriptive. In fact, the surprise factor is one of the guarantees that the email will be opened. However, getting the subscriber to be surprised is not easy, so you must know them in depth.
   
   
3. use, if possible, a maximum of 40 characters. A subject with more than 10 words is already too long, so the ideal length is between 6 and 10 words. This aspect is crucial in email queries from mobile devices. Email subjects should be as short as possible to be displayed on their screens.
   
   
4. try not to tell everything in the subject line. Synthesising a message is difficult, but not impossible. A subject line should be unambiguous and concrete, it should not raise doubts, but, above all, it is important that you do not tell everything in it.
   
   
5. the subject line should make a promise to the reader that will be fulfilled in the content. The subject line and the topic of the message have to match. Don't use a subject line to grab the reader's attention and then talk about a completely different topic.
   
   
6. reserve the first few characters for the most important information. Think that the most important things should be told at the beginning. Anything you want to say later may be irrelevant and the recipient will probably not read it. Don't miss the opportunity to tell the really important things at the beginning.
   
   
7. do not use your sender's name in the subject line. It is very common to make the mistake of writing the sender's name in the subject line. But remember that you have very little space and you have to be concise when using the first words of a subject line. Therefore, it is important not to repeat the same thing twice, as this will not bring anything new or interesting to the recipient.

8. one of the essential aspects of creating the best email subject lines is to incorporate the keywords that underpin your email marketing strategy.
   
   
9. test different subject lines - Learning how to create the best email subject lines involves constantly comparing the titles you choose.
   
   
10. create a sense of urgency. The new way of consuming the digital user is perfectly suited to create a sense of urgency, because the limited time frames force the subscriber to make a decision more quickly, sometimes affecting emotions and irrationality.
    
    
11. avoid toxic words: There are certain terms that ISPs (Internet Service Providers) identify as spam, for example, terms such as: "Buy Now", "Free", the use of capital letters, the excessive use of exclamation marks or symbols such as the dollar. There are updated lists of spam words that you should review on an ongoing basis.
    
    
12. numbers or data create a sense of trust and increase the credibility of the subject line. They also help to attract attention.
    
    
13. it doesn't have to appeal to everyone, it really has to appeal to your buyer persona. Never lose focus of who you want to target, because even if you have constructed the perfect email, the open rate will be much lower.
    
    
14. avoid being classified as spam. One of the main reasons for spam classification is the content or words you use in the construction of a subject line, so it is essential to avoid having an inadequate subject line and your message not being read.
    
    
15. Set a deadline in the subject line - especially if you have a lot of information to convey in the email itself, experts say you should include the deadline in the subject line, as this exponentially increases the likelihood of a response.

Finally, remember that the rate of opens and unique clicks is not only driven by a good subject line. Other factors come into play in an email marketing campaign such as the time of sending, the type of offer or service that is published, the number of sends that are made in a given period of time, etc. Thank you for reading us!
