What to Consider while Choosing the Time to Send Emails?

All the information mentioned here is based on case studies by recognized marketers and organizations. However, you should always remember that these are not the only things to consider. Some of the other factors that help you boost your email marketing game include the following:

1. Audience Demographics

Audience Demographics

No matter what your business niche or industry is, every business’s success is hugely dependent on its target audience.

Hence, knowing your audience is the most important thing for shaping your content and getting the right direction. This also applies when deciding the right time and day to send emails.

Analytic tools can help you find your valuable customers that are most interested in your emails. For starters, one of the major things to analyze is to check the age group i.e. if your emails are most clicked by young or old professionals.

This will help you decide a better preferable time for your audience. If the majority of your audience is young professionals, sending an email on Saturday evening can be less effective. Because these groups are more likely to stay out at night and are less likely to use their phone.  

Similarly, for older professionals, it’s not effective on weekend mornings as they might be spending time with their family.

2. The niche you work in


Niche is another very important thing for email marketing. It can also be seen as a subcategory of point no.1 because it helps you find the right audience category and choose a time accordingly. For instance, a niche like fashion, e-Commerce is more inclined to millennials, 

Friday or even Saturday morning is a preferred time for millennials to check emails. 

3. Frequency of emails

Frequency of emails

Time and frequency are two different aspects of email marketing. It is not necessary to send your business emails every week. Many business marketers prefer sending emails two to three times a month. 

4. Subject lines

The next thing on the list is Subject lines, yes, they are valuable or the most important thing when it comes to the open rate. It’s of no use to send an email at the right time if the subject of your email is not up to the mark.

On the other hand, if you have an eye-catching subject title that generates curiosity, your email will generate a high open rate. However, don’t forget to include a quality message as it will get you the best result. 

5. User experience

Your email’s appearance is as important as your email content. Everything that your readers can see should be optimized; this includes overall esthetic, paragraph organization, and more. What’s most important is to optimize your email for mobile.

It is not a lesser-known fact how in today’s world every content you put online has a vast number of people accessing it on their mobile phones.

The percentage of people opening their emails on mobile phones goes up to 42%. Optimizing content for mobile phones means keeping your paragraphs short, providing bullet points whenever and wherever possible and telling your story more with images than words.


The above-mentioned information affects email clickthrough rate and varies as per several factors like time zone, audience category, niche, and more. You need to consider all these aspects when sending an email but to do so you first need to identify your benchmark.

For starters, we will recommend you to start with the most preferred day and time like Tuesday morning. Later, experiment on different timelines and check what best works for your niche and audience.
