What is email deliverability?

Deliverability refers to the rate at which emails actually reach subscribers’ inboxes. An email delivery error usually occurs when an email has ended up in a spam folder or has been blocked by an ISP.

Getting an email to your inbox is not always easy. Many factors determine whether an email is delivered, blocked, or even filtered into a subfolder such as junk or spam.

So how do you make sure your email gets delivered? Fortunately, there are proven methods to prevent crashes and improve email delivery speed over the long term. This guide provides an overview of the steps that most businesses need to take to maximize email deliverability:

  • Authenticate your mail domain.
  • Maintain correct allocation of IP addresses.
  • Improve the subscription process.
  • Post spam-free threads.
  • Provide a center of preference.
  • Maintain clean lists.
  • Avoid spam traps.
  • Send emails that people like.

Marketers consider this indicator to be much more important for obvious reasons. Especially if you send emails in bulk, you want them to arrive in someone’s inbox, where you are more likely to be open.

What affects email deliverability?

You can improve email deliverability by following good email sending practices, managing your email frequency policies, maintaining a healthy email list, avoiding spam traps, warming up your mailing list, etc.

Before you can maximize your openness and engagement, you must first make sure that your emails are actually being delivered and are in your inbox.

First of all, delivery consists of three parts:

  1. Identity – Defines a set of protocols that prove you are who you say you are when you send an email.
  2. Reputation – Your sender reputation is a metric that shows how reliable your emails are. Each organization and Internet Service Provider (ISP) may have different ratings for you, but create positive subscriber behavior.
  3. Content – Is your message relevant to your audience? Do you combine bad writing with poor formatting to deliver a less impressive email experience to your readers?

Using strange formatting can affect the deliverability of your email depending on your previous sending patterns.

4 Key Factors Affecting Email Delivery

  1. Submit volume: The number of emails sent.
  2. Sending frequency: The number of campaigns deployed per week or month.
  3. User interaction: Individuals who open and click – and complain or unsubscribe.
  4. Qualitative: Bounce rate.

The best way to improve your domain’s reputation and keep it high is to send good emails that people will actually open and click. Subscribers can even share your emails if they are really valuable. All other advanced email delivery methods are technical in nature.

What is a good email deliverability rate?

A good email deliverability rate should be 95% or higher. Don’t confuse this with open rates, which can be significantly lower.

95% or more is considered a good delivery rate on behalf of an email provider. The bounce rate should not exceed 3%. As far as spam rate is concerned, you shouldn’t sound the alarm until it exceeds 0.08%.

Email segmentation best practices

  1. Choose the right email segmentation tool.

To get started with an email segment, you’ll need the right tool. Permanent Contact allows you to easily create contacts per contact, list memberships, and contact details.

2. Add the desired contacts to your mailing list.

Your mail tool does not have an updated list of the contacts you want. Solve this problem with reliable two-way contacts between your tools, especially if you collect your contacts in a regular contact system like CRM.

3. Make it as simple as possible.

Strive for simplicity when you are just getting started with list segmentation. To start, choose 2-3 segments that will make a big difference without introducing unnecessary complexity. A good starting point is to identify the main key values ​​of the buyer’s personalities and distinguish between them, such as type of business, location or purpose.

5. Remember user preferences.

Be sure to pay attention to your subscribers’ preferences – give your contacts what they ask for and don’t send them what they don’t want. If you’re collecting data based on your preferred email frequency and email types, take the time to create segments for it.

6. Synchronize your data.

One of the most important list segmentation techniques is data synchronization and relevance. If you cannot rely on your segments and data, you will run into problems. Make sure you collect the correct data in your forms, keep your organization clean with simple, well-documented processes, and clean up your data quarterly.

7. Combine mailing list segmentation with automation.

When you combine email segmentation with automation, you can send the most relevant messages at the right time. Then, set up your email automation to send your newsletters, emails, and activity-based emails at the right time.

How it works 

The email validation process begins with validating the syntax of the email address. Next, the verification tool checks if the domain name is correct. Once that is found OK, advanced technical processes begin.

Delivery time is cumulative. It’s not the result of one step, it’s the result of how other people react to your emails over time, and using that information to predict future recipient responses. Ultimately, it is a matter of sending emails that people want to read.

To achieve deliverability, start slowly and focus on engagement. By doing this consistently over time, you will build the trust of your subscribers. Besides, quality is more important than quantity.
