It is no secret that email marketing is one of the most effective ways to reach your target audience and grow your customer base. In addition, email is an effective way to retain your existing customer base and develop an ongoing relationship. However, with so many options available it can be challenging to know which are the best practices for email marketing for your SaaS product. Your target audience likely has an inbox flooded with spam, advertisements, and promotions from marketers trying to sell them something.
It’s essential that you stand out if you want people to take notice of your emails. Even though the world of email marketing has changed drastically over the last few years, the principles remain the same. If you want to see results from your email marketing efforts as a SaaS business, read on for some great tips on how you can get started today.
Timing Is Everything
The first rule of email marketing is that timing matters. If you send emails too frequently, you run the risk of annoying your subscribers. If you don’t send emails frequently enough, you lose opportunities to engage with your audience and inspire action. To determine the best timing for your emails, you need to consider your customer’s journey. What are their pain points? What are their challenges in adopting your product? When are they most receptive to your input? With that in mind, you can then choose when to send emails based on those milestones in your customer’s journey.
Best Days To Send Emails
Tuesday #1 | Thursday #2 | Wednesday #3 |
The best day to send an email is Tuesday | If you send emails twice a week, then always pick Thursday to send the second email. | Wednesday is not the most popular time to send emails but does perform very well as a 3rd option. |
For example, if you are sending an email series about best practices for using your product, the first email can go out when the user signs up for your service. The second email can wait a week or two and be sent when the customer starts using the product. The third email can be sent a month or so later, once the customer has become more familiar with your product, and the fourth can be sent about three months after the first email when the customer has been actively using the product for some time. In the next section, we share some examples of those types of emails.

People are likely checking their emails before going to bed. | Afternoons are also good times to send emails because people have likely returned from lunch and are checking out of work mode and looking for distractions. | Half of all people start their days by checking emails in bed. This can be a great time to reach people. |

Send The Right Content to the Right People
Another critical aspect of email marketing is to send the right content to the right people (at the right time). What do we mean by that? As mentioned earlier, the words in your subject line are critical to the success of your strategy. If your subject lines are boring or uninspiring, you’ll likely see a low conversion rate. Conversely, if you write subject lines that are highly engaging and relevant to your readers, you can expect to see a much higher open rate.

When it comes to the content of your emails, there are a few different approaches you can take. You can send informative emails that share tips and best practices. You can send promotional emails that highlight new features or products you offer. You can even send sales emails that prompt customers to buy something right away before a sale ends. Always try o personalize the emails using macros and if it’s a follow-up email then make sure you’re using the top tips to get a response.
Below you will find additional subject lines to test.

Don’t Forget About Email Marketing Creative
Even though the words in your emails are important, so is the imagery and creativity behind those words. This is the first impression your customers get from your company, so you want to make sure that it is a good one. With that in mind, you might consider investing in custom email marketing creative such as email designs and/or email images.
You can also use tools like Canva to design custom images for each of your emails. With Canva, you can create images to enhance your email marketing campaigns with logos, graphs, charts, and other visual content. Images are proven to increase engagement which can lead to more clicks, more opens, and more conversions.

Protip: Make sure you’re using “customization” macros in your email body and subject line to give the reader a personalized email marketing sequence. With COSLR, You can use {{first_name}} and {{company_name}} in the body so the user feels like the email is directed towards them. In addition, use a service that allows for customized images. These are effective as secondary follow-up emails.
To the left, you can see an example that we have used with the {{company_name}} and {{first_name}} macros. If the recipient is “Bob” and they work at “ACME Inc.” then the image text would read: “When the team at ACME Inc. Asks Bob why they close so many deals”
The email macros can be customized to any variable in your CSV contact sheet. Simply add the relevant column identifier (first name, last name, company, location, phone number, etc.) and then add the corresponding macro with that identifier.
