What is Email Deliverability?

The Email Deliverability Rate measures how successful you are in reaching real mailboxes. Basically, it represents the number of emails that were sent and delivered.

Receiving many spam complaints or having many bounces are some of the clear signs showing your deliverability needs improvement.

Check the four factors that causes an immediate impact on your email deliverability:

  • authentication: you must use some kind of email authentication service to avoid being marked as a spam sender;
  • reputation: it’s the assessment that your email address has, according to ISPs (Gmail, Outlook, and Yahoo, among others). They evaluate aspects such as fewer spam complaints, no spam traps or blocklists, fewer bounces, and consistent sending volume;
  • infrastructure: it’s the way your emails are sent, and the tools (hardware and software) used to send them. For example, MX records for your sender domain, shared IPs, IPs for high-volume senders, and IPs for time-sensitive campaigns, among others are considered infrastructure;
  • content: it is defined by what texts, images, and videos (and other kinds of communication) are you sending to your subscribers through email. 

There are also other factors that are considered positive to your email deliverability, such as:

Email Delivery vs Email Deliverability: what’s the difference?

Email delivery and email deliverability refer to different stages of the sending process. However, both are frequently taken as the same thing. It’s important to understand the differences between them in order to improve communication through email.

Email Delivery

It is the stage when the email is delivered to the receiving server. Sometimes, senders have an acceptable delivery, but the email deliverability is very far from the ideal. 

This is due to the fact that an email can land in spam folders, which means the message never got to its final destination, the inbox.

It is in this stage that bounces happen. In this case, Email Services Providers (ESPs) will inform you why the emails weren’t delivered through an error notification. This way, the sender will know if the problem was caused by a temporary situation (soft bounce) or a permanent one (hard bounce).

Senders must read it attentively and try to solve the issue as soon as possible to prevent bounces from happening again.

Email Deliverability

It is the stage when the email arrives at the receiving address (real inboxes). After the email leaves the server and is directed to its destination, there are some obstacles to be overcome, such as spam filters.

As it is related to engagement, adequate email deliverability is hard and constant work. Many factors are taken into account in this stage of the sending process, for instance:

  • Bounce Rates must be as low as possible to guarantee good deliverability;
  • Open Rate, in turn, must be high;
  • Unsubscribe process has to be easy;
  • Click-through Rate has to be high;
  • Your domain mustn’t receive many spam complaints.

These factors are some of the characteristics associated with good deliverability. Monitoring KPIs and marketing metrics is indispensable to understanding how your audience is receiving your content.

The analysis of these numbers will establish what the next steps are in your marketing campaigns. 

Why is email deliverability so important?

What’s the point of writing the best emails if they are going to land in the spam folder? Or worse, they might bounce, returning to you? When you think about these questions, it’s easy to picture the importance of email deliverability.

Following, you can check examples of powerful deliverability.

  • The ability to land in real mailboxes will provide a high return on investments: to happen, email marketing campaigns need investment. If the messages are not delivered, you have just lost money. However, if you reach mailboxes, this investment will be compounded, boosting your ROI;
  • Good deliverability will keep you away from blocklists: a nightmare for every email sender is to be classified as a dangerous agent in the online world. Having a good online reputation is the ultimate desire here. Protecting your deliverability is the same as taking care of your name in the online universe;
  • Understanding deliverability helps you understand your audience: users engaging or not with certain campaigns is fundamental to have some insight about how strong your strategies are. If they don’t even land in mailboxes, it will be impossible to study your audience.

There is no need to further explain the importance of protecting your email deliverability. It is just as important as protecting the physical location of one company. 

You do everything to keep it clean, safe, and free of dangers and threats, right? You should do the same to email deliverability.

How to improve your deliverability?

Your email deliverability needs constant care. Improving your ability to have your emails delivered is one of the biggest challenges marketers face. Nevertheless, it all comes down to a few requirements.

If you pay attention to them, you will be able to achieve more success in email marketing campaigns. Let’s get acquainted with them, shall we? 

Take care of your sender score

Senders that have a faulty reputation usually have trouble with email deliverability. Protecting your reputation as a sender is fundamental to making your emails delivered. There are some positive practices that you should do to protect your sender reputation, such as:

  • your sending volume must be consistent and organized, that is, sending emails at random moments is not an option if you want to cause a good impression in relation to ISPs;
  • always clean your email lists, to remove invalid addresses and other kinds of emails that can destroy your reputation;
  • be aware of spam complaints, focus on the content you produce, get permission from the user to send emails, and let subscribers choose the frequency of the messages, as well as their types;
  • do everything you can to stay away from blocklists, respecting the security guidelines present in the legislation.

Such actions are the most important ones when we talk about protecting your email deliverability. Not only will you have a better online reputation, but they also will make you provide a better experience for your subscribers. 

Use sender authentication

Using authentication protocols is primordial to eliminating any problem related to having your emails delivered. These protocols help ISPs in their analysis to determine if an email is legitimate or not.

This is even more essential when you use services from a third party to send emails on your behalf. If the pieces of information, related to the origin of the email and the service used for its delivery, spam filters will be activated, causing a decrease in the email deliverability.

You need to authorize and legitimate every domain or sender IP that is employed to send messages to your audience. When you don’t do that, the messages sent through other services will be taken as spam, which is terrible for your online reputation.

Emails must be properly authenticated. Setting up an SPF record to verify and authorize addresses to send emails under your name is recommendable to protect your domain and improve your email deliverability.

Segment your audience

Every audience is plural, which means emails must be personalized. The time of writing messages as if your public were composed of only one profile of consumer is long gone.

That’s why you have to segment your audience, according to the criterion you see fit. For instance, you might want to consider the location, gender, behavior on your platforms, stage on the sales funnel, and age, as smaller groups that belong to your target audience.

Email list management is the first thing you have to do when planning a new project. This way, you can better analyze which segment can have more engagement in a marketing campaign.

Never treat your subscribers as if they were all the same. They are all different, and these differences should be explored, never ignored. This is one of the most important strategies to improve your email deliverability.

Keep your lists clean

Some emails never get to see their recipients, partly because of poor quality of email lists, plenty of bounces. That’s why marketers must clean email lists frequently, removing addresses that are unengaged in responding to your pieces of communication, identifying invalid addresses to delete them, and locating disposable addresses as well.

These email addresses might be the reason why you are receiving spam flags. Cleaning your lists can lead your company to a higher Open Rate and Click Through Rate. This will help you lower bounces, make you more respected as a sender, and the list of benefits goes on.

Using an email checker tool to verify and validate email addresses is one thing that helps you keep your mailing lists clean.
