Posted: Tue Dec 03, 2024 10:27 am
We have mentioned on numerous occasions in our articles on this blog how important it is to define a good subject line for your mass emails. Because, without a doubt, the subject line is key when it comes to the user deciding whether or not to open your email, since it is -in practically all cases- the subject that we indicate that will draw our attention or, on the contrary, will make us discard the email without further ado. However, we are almost sure (and hopefully we are wrong), no matter how much advice we give you, that you also end up leaving the definition of the subject line for last. Yes or no? Huh?
For this reason, and because we don't want the first impression that the user gets when reading that subject line (which you probably wrote ten minutes before sending the email) to be negative and harm your brand, in our article today we want to share with you five great key tips that you should mark as mandatory every time you define a subject line.
Five easy and simple tips that will not cost you anything to apply to your subject line, and that will surely save you from a bad first impression on the part of the user who receives your email.

So, as we want your emails to not go unnoticed, we want to share with you some tips to create powerful subject lines for your emails.
The most important information always at the beginning
We're not telling you anything new when we say that people read from left to right and that our eyes will always go first to the beginning of sentences. That's why, don't hesitate for a second, communicate first what is key for you, maximizing the opportunities to capture the recipients' attention.
For example, if you want to communicate a discount or promotion, place the keywords that will attract the user's attention at the beginning of the subject line. Take advantage of the only opportunity you will probably have, in that first quick glance that the user takes at their inbox, and go for the win: make the phrase of your subject line direct and contain the key information at the beginning , making it something relevant that will be noticed by the recipients.
Be brief. Better a little and quality than a lot and "bad"
It is also important to add to the previous point the consideration that the sentence we use as the subject must be brief. In this way, we will ensure that the user quickly reads everything founder email lists we want to convey in the message - as a summary - without our sentence being cut off at any time because it is excessively long, and thus you will also avoid not adapting to the format that the service provider considers when displaying their emails.
While it is true that there is no set number of words, nor a reference that we can give you to take into account; but, in any case, we all know when a sentence is too long to be the subject of an email (a subject that, in a certain way, is the essence of our message)
Consider including emoticons and join the trends
Nowadays, absolutely everything we perceive is a source of inspiration for our brand. The more references we have, the better. It doesn't matter if we are inspired by a movie or by a supermarket brand's advertising brochure. Everything is a reference and everything is of interest.
3 types of subject lines to increase the opening rate in your eMail Marketing strategy
For example, being informed about what is happening in other sectors, areas or society in general, can make us - somehow - find brilliant inspiration with a perfect common thread that makes us transmit a unique personality to the public , breaking away from the established canons for our particular sector. Don't you think so? And this is just one example, but there are many current situations and trends that can inspire us and serve as a reference.
And why not? Imitate fashions and trends. There's nothing wrong with that.
Avoid forbidden words at all costs
We all know that, in the case of Email Marketing and email in general, there is a basic rule which consists of not using, at any time, those forbidden words that can damage our reputation. Some such as “free”, “make money” or “urgent” can be clear examples of this.
As an expert advice in Email Marketing, we recommend that, if what you are looking for with your campaigns is to boost your results, you completely avoid prohibited words, since email providers will take this into account to rate you negatively.
Carefully review the words you use and try to completely and absolutely disassociate them from all those that are associated with SPAM.

Make the subject line as personal as possible
This tip is, once again, a point that we have added to our articles on many occasions. And, without a doubt, it is due to its level of importance.
Nowadays, users -in their purchasing processes- are no longer just looking to buy a product, but to link up with a brand, to buy a service. To be loyal to the brand. Not to consume for a specific product, but for a brand. Because we share the brand's lifestyle, we share its tone, we share its philosophy... and we are part of it.
And if we - as users - want to belong to a brand and be linked to it, it goes without saying that we will also seek a reward for this from the brand. And what less than to feel special and cared for by it?
Use but don't overuse emoticons in your eMail campaigns
Personalizing your emails is essential to make users feel part of your brand. Use their name in your email, or one of their interests, even their geographic location… although it may seem unimportant, these are small details that draw the user's attention and that they will undoubtedly like.
For this reason, and because we don't want the first impression that the user gets when reading that subject line (which you probably wrote ten minutes before sending the email) to be negative and harm your brand, in our article today we want to share with you five great key tips that you should mark as mandatory every time you define a subject line.
