How to Choose the Best Mass Email Service?

For any business, it’s very upsetting to know that the mass emails don’t reach their subscribers. Yes, surprisingly a lot of times such emails land up in spam instead! So it’s important that you chalk out a strategy before choosing a bulk email sender so that you get the best one suitable according to your requirements, infrastructure and budget.

Here are a few things that you can keep in mind to create more revenue from your customers. 

1. Check your Subscription Process

Verification of the email-Ids is important as it prevents your email from being marked as spam. Your email subscription process should be double opt-in. The approval of the email users receiving the promotional emails is necessary, otherwise, a single opt-in process would lead to either unsubscription, deletion of the mail, or customer marking the emails as spam.

So, Double opt-in is a big yes!

2. Segment Your Mailing List

Every email user has different needs and have to be catered accordingly. By using your CRM database you can collect the different attributes of the user, and then segregate them on the basis of the persona.It is an effective way to increase engagement and convert the subscribers into customers!  

3. Track User Behavior

Every user creates a journey or persona of their own as they use your products or services. Tracking and analyzing their spent time and type of products they are browsing, can create a highly personalized campaign for them.  

You can further place the users in 3 categories- Interested → Engaged → Re-activate. This will help you segment your customers and then target them with relevant emails.

4. Follow Email Authentication Process

Checking for email authentication process is the major deal-breaker. The ISPs depend on these practices to filter the emails into spam. Enabling DKIM, SPF, and DMARC for your email delivering domain will make your campaign much secure.

5. Warming Up IP/Domain

Another process that is highly recommended is the warming up of IP and domain. What is that? So, before you start sending those mass emails from your domain, start the warm-up process which involves slowly increasing the volume of emails that you are sending in a day.

Also, don’t forget to monitor the engagement metrics, reputation, inbox placement rates etc. This will boost the per day volumes, create a high reputation, and ensure smooth inboxing that will help to make an email program successful without any issue.   

6. Create Neat HTML Campaign

Content is the key in any campaign, as it communicates the image of your brand to the audience. Engaging and attractive campaigns can kind of fuel the revenue growth. Here are some good practices to create attractive campaign for your audience.

  • The HTML templates should have a simple and clean design.
  • No extra CSS styling.
  • An equal proportion of text and image.
  • No commented code or map tags.

Personalization of the content also gives good results. A personal touch, like including the name of the user in the subject line can enhance audience engagement.  

7. What is Your Mailing Domain?

Using the domain of your website is always recommended. However, if there is a certain risk involved, then you can go with the sub-domain of the main website and then build your status on it. 

Also, make sure that you don’t use the same domain for transactional and promotional communication as it will increase the chance of your important transactional emails landing right into the customer’s inbox.
