There’s no one answer to the question “How do I increase my email deliverability?” because there are a number of factors that can affect it. However, here are a few tips that may help:

1. Use Custom email list segmentation

As you may be aware, there is a huge correlation between email engagement and deliverability. Email list segmentation refers to the division of your email subscribers into smaller segments based on specific criteria. Segmentation is also used as a personalization tactic to deliver more relevant emails to a specific group of audiences and subscribers usually based on their locations, interest, purchase history, and lots more.

Email segmentation is useful to enhance email deliverability because an email sent to a large number of people is usually spammed in email systems.  Spamming means that the emails are unsolicited, hence they are marked as junk. Most spam emails are also considered as sent for commercial purposes. They are usually spammed because the email algorithm thinks that your email recipient might not be interested in them.

Mailchimp, one of the most popular email service providers once completed a study where it realized that email segmentation could be very important to mail sending. In the study, it was identified that segmented email campaigns have a higher open rate than non-segmented campaigns. Segmented campaigns also received 100 percent more clicks than non-segmented campaigns. In a similar version, segmented emails experience more than 4.65 percent fewer bounce rates than otherwise. Above all, segmented emails receive fewer abuse reports and unsubscribe rates than unsegmented ones.

When you put all of these statistics together, it means only one thing. Email recipient gives more attention to what they can relate to than otherwise. Therefore you must be ready to segment your email based on a few demographic and other objective factors as to why you are sending the campaign.

2. Send emails from trusted IP addresses

Let us face it. The major war against email deliverability is spamming. It in fact continues to be the major annoyance of email users. With a thorough watch on this, there is an improvement already from the previous statistics known. Statistica especially assessed that 71 percent global spam rate in 2014, as against 52 in 2017. The reason for the improvement is that ISPs continue to wage wars against email spamming. To do this, one of the major things to be sure of is that your emails are coming from a trusted source and IP address. Once an email algorithm sees that your IP seems suspicious, there is a high chance that your email won’t reach its destination. So, you will have to build IP credibility to avoid your campaigns being spammed.

All an ISP wants to ensure is that recipients are actually opening and engaging with your emails via a trusted IP address. Once this is the case, the volume of your emails that get delivered to the audience will increase. You might need a close watch on your IP reputation if you have not already done this.

3. Keep the email list clean and updated

Email list refers to a file of emails created after compiling emails from those who are interested in your offers whether via marketing funnels or lead magnets. Care must be taken not to just gather emails from anywhere. ISP usually wants to confirm that your email recipient has at one point or the other interacted with you.

A clean email list means fewer spam complaints. You will reduce costs on undelivered emails if you keep a clean email list. The best way to build a clean email list is to ensure that the process of retrieving audience emails is very organic. Take the email of only those who are interested in your business and nothing more. Your funnel and lead magnet should be focused on getting the most organic leads and emails for you. With a clean email list, there is a high tendency that you will not be marked spam by recipients.

4. Use two steps opt-in-method

You will want to be double sure that your email list consists of prospects and only those people who are actually interested in hearing from you, not just some people who have subscribed to you by mistake or for temporary reasons. To ensure this, you have to simplify the opt-in process for those who are interested in subscribing to your email. One efficient way to do this is to allow a two-step confirmation process. It is believed that if you make a mistake clicking “subscribe” at first, you would at least not make a second mistake when the confirmation question pops up. You also will want to give your subscribers the chance to unsubscribe at any time or your campaigns would not be effective. These processes should be created in a way that is incredibly easy.

5. Write a clean email subject line and preview

When writing an email as a part of your campaign, you have the chance to either hook or lose your audience almost immediately. One of the ways to either lose or hook them immediately is with your subject. If it is catchy and compelling, you win. Otherwise, you might be losing just another prospect. From your subject line, an email recipient could tell if this is what he should open and read from or otherwise. That is how powerful your email subject is in a campaign.

In lieu of this, the business insider has said that your email subject line could be a guarantee that it will be read. Not adding any subject at all might mean that your audience wouldn’t even bother to check at all. You have to be very careful with your subject lines too. That your subject is expected to be catchy and compelling doesn’t mean that it should be spammed. The moment your subject line makes your email look like it is spammed, the ISP’s filter would usually put them where they belong. Some people also don’t read emails with too good-to-be-true subject lines. Such people will intuitively spam your email if you have not written your subjects the right way.
