Ever since there has been a boost in the smartphone usage, email marketing has regained its solid prominence in the world of online marketing.

Email marketing is considered to be one of the most effective marketing techniques, generating desirable results for a lot of businesses.

Apart from creating brand awareness, email marketing also helps in your search engine optimization, and increases the conversion rates of your business.

But all of this can only be done if the rate of your email deliverability is high. Email deliverability is a measurement of the rate at which emails get delivered into your recipient’s inbox.

Often times, your emails end up landing into the spam folder or get blocked by the ISPs (Internet Service Providers). This happens because WordPress uses the PHP mail function to send out emails.

Most times, WP hosting providers do not configure this mail function properly, or consciously block it to ensure that their servers aren’t used to send spam.  

In that case, the amount of effort you might have put in to carve the most enticing email will amount to zilch. What good is an email if it does not get delivered to your target audience’s inbox?

In other words, your email marketing efforts can be judged by the rate of your deliverability. Of course, your emails have to be segmented, enticing, and targeted. But first you have to ensure that they reach your audiences.

Increasing your deliverability rate should be at the top of your priority list if you want desirable results from your email marketing campaigns.

Increasing Email Deliverability from Your WordPress Site

As a business, it is highly likely that you use your WP emails almost on a daily basis.

Whether it is to send out notification emails, reset passwords, or raise general awareness about your brand, WP emails are extremely crucial for your daily operations.

Having said that, there are certain WordPress Plugins that you can use to ensure high email deliverability rates, free of cost!

The top 5 WordPress Plugins to Improve Email Deliverability 

1. SendGrid

SendGrid is perhaps the most famous Plugin to use for email marketing. Using SendGrid, you can send transactional and marketing emails from within a single platform.

SendGrid is also used by huge companies like Uber, Airbnb and Spotify to improve email deliverability. Personally, I have used it for a long time now. And its consistency in quality has always floored me.

Although it is a paid service, they also have a free plan which allows you to send up to 12,000 emails a month.

This is an ample amount if you are a small or mid-sized website. The paid plan starts at US $9.90 per month for up to 40,000 emails.

If you are a novice at using WordPress, then it may not be the best plugin for you, as it will take you a lot of time to get comfortable with its features.

On the other hand, if you’re comfortable with CSS and HTML, then it is the go-to plugin for you. All you have to do is install and activate the Sendgrid WP plugin.

After that, the plugin will ask you to connect your WordPress website to Sendgrid, using both a username and password provided by SendGrid or by adding an API key.

Here, I recommend using the API key method, as it is more secure.  You can easily figure out the rest of the steps as you keep moving forward.

2. MailGet

This is another immensely popular WP plugin amongst online marketers. This plugin helps in designing emails, campaigns and newsletters, etc.

The reason for its popularity is the fact that it is very easy to use. It automatically mitigates the spam and bounce rate of your email via its list cleaning mechanism.

Using this plugin, you’re also also able to send personalized messages to your potential customers, which will further help you in increasing your business.

It also provides you the feature to add bulk contacts to your account, using a signup form through API.

In addition, you can use the drip email feature to send sequential emails to your customers through a campaign.

All in all, this WordPress Plugin has a lot of features that you can put to use in a simple and straightforward manner. For small and mid-sized businesses, this plugin is, perhaps, the best bet!

3. Elastic Email

Elastic Email is another robust email marketing tool that has an amazing delivery system.

The flipside is — an official plugin for WordPress hasn’t been created yet. So you’ll have to get your WordPress site integrated with Elastic Email using HTML integrations.

If you’re a digital marketing agency, Elastic Email has to be the best option for you in this list.

Using this plugin, you get a 100% white labelled dashboard with the option of adding multiple domains and accounts. This will help you set up a self-service platform to sell it to multiple clients.

You may want to check out their pricing system for yourself as it is a bit complex in relation to the other WP plugins. 

4. SendPress

SendPress is a great newsletter plugin that will certainly help to improve email deliverability.

Using this plugin, you can design the templates and edit the contents of your newsletter, according to your preferences.

Two of the key features of this plugin are that you can gain unlimited subscribers, and send an unlimited number of fully responsive newsletters.

This plugin also lets you track your progress using its tracking facility. The tracking facility will also help you keep track of your clicks and unsubscribes.

This will further help you determine the faults in either your WP website or email marketing methods.

You can also customize the custom form, page and subscription widget. Its theme style is also extremely easy to use.

If you want to have a comprehensive plugin to send newsletters to your subscribers, SendPress should be your one stop destination.

5. MailFlow

This WordPress plugin has made the email automation process smoother and more efficient.

Using this plugin, you can build the sequence of your emails in a flowchart pattern and see them all at the same time as well. You can directly integrate this plugin with your WP website.

This plugin has a unique tagging mechanism which will help you with tagging a contact during a campaign, and you can easily target your emails using these tags.

This plugin has made the process so streamlined that now you can manage all the different campaigns meant for various websites in the same place, using this plugin.

Apart from that, MailFlow also comes with a safe API which can be used to manage the different elements of your email marketing campaign.


There are hundreds of other WP plugins as well that I have missed out for various reasons, which include their cost and efficiency in operations, etc.

Although each plugin has its own pros and cons, these above-mentioned 5 will are most likely to fit your bill if you use them correctly.
