Exercising Email Hygiene in 2022


The most common causes of email bounce and steps you can take to prevent this using email verification

Email marketing has remained an important sector for organizations in the ever-expanding digital realm. A high email bounce rate, on the other hand, should be addressed as soon as you become aware of it. It’s because a high bounce rate impacts your campaign metrics and might be seen as a red signal by email service providers, which makes it troublesome for your email deliverability.

Emails that ‘bounce’ was unable to reach their intended destination. Using the example of sending 1000 emails and receiving 15 bounces, a bounce rate of 1.5% is calculated (take bounced emails, divide by total sent, and then multiply by 100).

Email bounces might fall into two categories. The recipient’s server could not accept the email, resulting in a hard bounce. However, if it bounces back because of anything other than a full inbox, it implies the recipient’s server acknowledged it. Regardless of the reason for a high bounce rate, it is critical to figure out what is causing it to find a solution. This solution might be using qualitative secure email validation services and email hygiene.

Here are some of the most common causes of email bounces, as well as several workarounds that might help you reduce your bounce rate.

Full mailbox

When an email account has been inactive for some time, the unread messages accumulate, resulting in an overflowing inbox. There is no room in the inbox for any more emails once it has received all of the ones it has already received. The recipient should be removed if they seem inactive in the database.

Email that was not delivered

If the server is down for any reason, emails will be returned as undeliverable. It’s possible the server has stopped working if you’ve received many bounces. The server may have gone down, it may be undergoing maintenance, or worse, it may have gotten overwhelmed.

It’s possible that your emails are being rejected because they are too big or too little in terms of size and format. The size of the emails you receive may be restricted by your email recipient. The size and structure of your email campaigns should be checked to verify that they are compatible with most email servers.

Inactive address

Bounced emails are often the result of erroneous or invalid email addresses. The email will not be sent if the recipient’s email address contains typos or grammatical errors.

You may enhance the quality of your data and the efficiency of your operations by using an API to validate email addresses as they are input. Adding MORE to your sign-up forms is simple because of its simple API. It verifies the validity of email addresses in less than a quarter of a second after they are entered in. As a result, marketing initiatives will be more effective due to this.

While verifying email addresses may be a time-consuming and labor-intensive process without the aid of CORE, it can also significantly boost your marketing results by reducing the amount of bounced emails.

Automated or out-of-office messages

The intended receiver of your email may be either on vacation or otherwise unable to access their inbox. They may establish an auto-reply that serves as a placeholder until they return in certain situations. You may get a bounced email report even though you didn’t get a response from them since they’re acting as the recipient.

The poor reputation of the sender

Email reputation is important in the world of email. Those are the impressions the email service provider has about your email address. If you are rated low on the list, many of your emails will not be sent to the recipient’s inbox. Using list segmentation, you can ensure that you send emails to the correct recipients at the right moment.

The attached file has an error

Email hosting providers often restrict file attachments. Attaching huge files or sending emails in an improper format may result in the recipient not receiving them. Your email may also be rejected if the attachment is too big. Make sure you’re familiar with the rules of your email provider.

DNS verification was not completed

An IP address must first be matched to each email address’s domain name to send data. The mail server uses DNS to find the recipient’s email address to deliver the email.

Configuring your public DNS records can help mail servers discover you and your email list, so do it now. Other mail servers will trust you to receive their emails, and you can set up your mail server correctly.

IP ranges that have been blacklisted

Spam mail server IP addresses and domain names are publicly shamed on a list of known spammers. Systems administrators, programs, and subscribers with a special requirement for automatic updates refer to these lists.

An IP address or email address is used to identify each item on the list. When a mail server goes online, this data serves as a unique reference, much like a fingerprint.

They frequently vary because these blocklists are administered by various organizations with differing definitions of spam. As a general rule, the server’s speed, amount of emails sent, spam results submitted, and security are all considered.

A sender’s IP address may be used to transmit spam if someone in the same IP range is spamming. Emails from the same IP address as a corporation known for spamming may be considered spam and not sent to the intended recipient.

Internet Protocol addresses are added and removed from blocklists for various reasons. Even if one of your emails is marked as spam by a random receiver, your IP address will not be added to a spam blacklist. It’s possible that your IP will be blacklisted if you send a large number of emails that generate a large number of spam complaints.

Contacting the list manager and going through the procedure to prove that you aren’t a serial spammer is the best way to remove your IP address from the blocklist. To protect yourself against cyber assaults, you may want to improve the security of your server.
