Email Verification

What is email verification?

Email verification is a service that identifies an email address validity and checks whether it belongs to a real person.

The main purpose of email verification is to ensure that a real person having a valid email address will receive your sent email.

In other words, Email Verification helps clean up your email lists to improve deliver-ability, identifies possible bounces and spam traps, helping you reach your actual customers.

Why do I need to verify it?

Email is the most preferred and economical method of sending messages and communicating with the rest of the world. Apart from being economical, it is very fast too, the recipient receives the emails instantly.

There are various reasons, which prohibit an email from reaching its proper receiver. The most probable reasons can be the individual might has changed their email address, or no longer using it or the domain of the inbox provider is no longer valid or the company to whom the email belongs may have closed or any other reason.

So when you send emails to a non-existing email address, it will increase the chances of your sender IPs will be blacklisted, or your email sending account will be blocked if you are using any 3rd party service provider.

Email Verification will improve your sender reputation and help you to get better email delivery results. And you don’t have to waste your precious time and money on those non-existing IDs.

Hence, the email verification will become the most important process in your email sending.

Why I need to verify

Which email verification service I need to choose?

Many verification tools are available online which can help in the email verification. The main purpose of these services is to verify the email addresses.

There are numerous services, which aims in providing this service. EmailVer is one of them to provide such service and preferred by many users due to accuracy and economical pricing structure.

Email verification is very much essential, especially in case of lead generation since you do not want to lose any of your leads due to a typo or due to other reasons. Any lead can be your potential client.

Any business that sends emails to its users soon finds themselves in a situation where they need to verify their email addresses. Whether it be to lower the bounces, prevent fake account sign-ups by using the temporary email accounts, prevent spam traps, or just keep their email list update by removing the old email addresses from their mailing lists.

How exactly does email verification work?

EmailVer’s email verification process works in 3 stages as follows.

  • Duplicate and Syntax check: In this first stage of validation we removed all the duplicate IDs present in your database along with improper syntax IDs (i.e. [email protected] ), syntax checker will check whether an email address format is correct or not— no spaces, commas, and all the @s, dots, and domain extensions are in the right place.
  • Invalid Domain and Disposable email check: In the second stage of the email verification process. Domain check allows you to be sure the domain name the email address is hosted on actually exists, we will check the MX record of each domain of identifying its validity, and then we will check the domain is part of the temporary domain provider or not for the disposable IDs check.
  • Valid, Invalid, and Catch-All IDs check: In this last and most sophisticated stage of email verification. We will ping each email address with an EHLO message, then awaiting the response from the recipient’s email server. The received server-response will confirm the email address exists on the server and is active.
Email Verification -How it works?

What is email list scrubbing?

Email list scrubbing means to remove people who will never be going to interact or open your emails.

Scrubbing will not only reduce the size of your list, but it will improve the list’s overall success too.

A classic example of quality over quantity scenario.

By removing non-engaged subscribers, you might scrub your email list of anyone who hasn’t engaged with one of your emails in 90 days, for instance.

You should send emails to only those who interact, open, click, or reply to your campaigns.

Keeping your lists hygienic by scrubbing them should be an integral part of your email marketing.

We recommend you scrub your lists from time to time.

Email List Scrubbing

How to scrub your email list?

  • Segment your list into active and inactive data
  • Clean inactive emails through a list cleaning tool
  • Send re-engagement campaigns to your subscribers
  • Finally, remove inactive subscribers from your list

When should you scrub your email list?

  • A sudden drop in your open or click-through rate on your recent campaigns.
  • An unusually high number of unsubscribed.
  • An increase in spam complaints on your email campaigns.
So, if you have a paying a lot to your ESP, you can save money by cleaning your list.

It has multiple other benefits as well such as higher open rates, more clicks, and, ultimately, more sales.

So how can you improve your list hygiene?

  1. Email list verifier
    You don’t want to continuously send emails to invalid email addresses because this can hurt your delivery metrics, especially your delivery rates. The best method to counter this situation and maintain your list hygiene to use an email list verifier. It will automatically check every address before sending any emails and improve your list hygiene.
  2. Remove inactive subscribers
    It’s a good idea to remove inactive subscribers from your list from time to time. Many sender remove subscribers who haven’t opened or clicked on their emails. Subscribers who aren’t opening your messages are not valuable to you, and if they stop reading your messages, they may forget why you are sending them and mark your messages as spam.
  3. Segment rather than delete
    If you are sending emails daily, try weekly or monthly emails instead. Also, consider adding in an existing offer or content that is relevant to them and will capture your audience’s attention. This is why personalizing the message is so important!
    Keep segmented your data of active and non-active subscribers to gain more benefits from your list.
  4. Avoid the spam filter and spam traps
    The main reason of not getting higher delivery rate is the spam filters, it could be because of your email content (subject line, link present in email), hence many senders no considering list cleaning so not only they will able to verify the list, but they will be able to remove the spam traps present inside their list.
How to improve list hygiene

Is your bounce rate higher than average?

Your average email bounce rate tells you the percentage of emails that were not delivered to your recipients. Your undelivered emails can be grouped into two different categories, i.e. soft bounces and hard bounces.

If you are getting a higher bounce rate than usual so, you must take further steps to take it down under the acceptable threshold.

What is an acceptable email bounce rate?

The accepted threshold for bounced emails may vary and it would be somewhere between 2 to 5%.

This means for every 100 emails you send, 2-5 will be returned to you.

It might just be a temporary problem that resolves itself in your next email send, although if you notice a bounce rate greater than 5%, you need to take immediate steps and consider the option to clean your list.

How many spam complaints are you getting?

Spam complaints can happen even to good marketers who are sending to opt-in email lists only.

The complaint ratio used to be underestimated, but recent research shows that 27% of deliver-ability issues were caused by a lot of spam complaints.

The complaint rate is calculated as the number of reports as spam complaints out of emails sent.

For example, the 0.1 – 0.3% complaint ratio is considered acceptable and often seen among good senders, at it can go up to a maximum rate of 0.5%.

More than this threshold, ESP can stop your mailing account and your delivery might be hampered.

While you may not be able to achieve zero complaints, you absolutely can reduce and maintain your complaint rate at the acceptable level to increase your email deliveries.

Why is your email marketing not producing results?

Why is your email marketing not producing results?

Email marketing has the highest return of investment out of every other available marketing technique.

If your email return of investment is low it means is low, it’s more likely because no one is getting your emails or it went to their spam/junk folder.

If your emails are going into a spam/junk folder or bouncing back to you, they’ll no going to help in your marketing. Do need to disappoint since there are several ways to resolve the problem.

  • Clean your list and keep your list up to date.
  • Use a reply-to address so your customer interacts with you, using a non-reply-to address give a signal of spamming or make your email service provider think you’re sending junk emails.
  • Always segment your email lists so that each customer will receive a customized email.
    They’ll engage with your content more, which ESPs will see as a good thing.
  • And don’t forget to track your emails with an email marketing tool of your choice so that you can view reports on your campaigns for open, click-through, bounces and unsubscribers, and fix any mistakes that are lowering deliver-ability rates.

86% of organizations ranked email as their primary communication channel.
Hence, Email Verification plays an important role to protect your sender’s reputation and will ensure that your emails reach your recipient’s Inbox.
