According to Clairvoyix tweet, hard bounces are a result of invalid or non-existent email; there is an error in letter or number, or such an email has been closed. Bounced email occurs when your email fails to deliver, gets stuck on the way, or when the recipient does not get the email. In email campaigns, the higher the bounce rate, the less successful the campaign will be.

The bounce rate could be in two forms; the hard bounce and the soft bounce. The hard bounce is a result of a closed, invalid, and non-existent email address. Mails sent to these email addresses will not be delivered because the recipient addresses are not functional.

How Does Email Verification Software Work

On the other hand, soft bounces are a minimal and temporary problem. The emails do not get delivered for several reasons, such as filled recipient inbox or connection errors on the recipient's device and a host of others. In this case, the recipient's mail server may temporarily hold the mails till the problem gets resolved. In ensuring that your email campaign is successful, you have to put all measures in place to ensure that the recipients receive the mail.

Tips to Verify an Email Address

One of the proven ways to reduce your bounce rate in an email campaign is the use of an email verifier. The email verifier helps to check the validity of the recipient's email address and ensure that your email gets delivered.

The email verifier can be used to track the validity and verify if an email address. Once the email verifier shows that the email address is invalid, it automatically flags it and is removed from the mailing list to prevent the mail from bouncing and get ranked among bounce rates. The following are the tips to make sure your email never bounce:

Most times, hard bounces are hard to detect, the reason for the email bouncing may take a long to be identified. However, the reason is not necessary, what is essential is getting to know that the email address is invalid and do not hesitate to remove it from your mailing list or newsletter subscribers.

3. Verify and Authenticate Email Addresses

4. Resolve Soft Bounces

Soft bounces are a minimal and temporary problem.

Soft bounces are also bad for cold emailing; you can send a message that should be opened urgently or acted upon before the expiry date and time.

5. Send Emails Regularly

When you send emails at regular intervals, you are increasing engagement and the relationship between you and your subscribers or customers and, at the same time, lowering your bounce rate. Regular email exchange between you and your subscribers enables you to identify which recipients do not open or even read the email, talkless of replying or acknowledging it. This way, you can reduce your bounce rate.

6. Allow a Permission-Based Mailing List

Another tip to make sure your email never bounces is to have an email list where every subscriber or customer has consented to receive your emails, newsletter and be part of your mailing list.

Your subscribers have a reason for joining your mailing list; it is mainly because your content interests them. You should ensure that the contents that drew their attention to your newsletter or mailing list are what you keep feeding them to avoid bounce.

When subscribers or customers no longer get the content relevant to your niche, they stop opening your mail or label it spam. For example, a healthcare organization whose newsletter contains tips on a balanced diet, regular exercise and leads to maintaining a healthy lifestyle, when they start advertising drugs and sending unsolicited emails to promote these drugs, they risk their mail being bounced.
