As per extensive research by many tech giants, most businesses prefer email marketing over other channels because they want to create awareness among the right prospects. The cut in the email deliverability rate impedes the performance of marketing strategies. Notably, email marketing experts found the solution to boost your email deliverability rate and give an uplift in your marketing strategy. The same has been addressed by us in this whitepaper.
Email verification and validation is a process that performs a detailed breakdown of emails in the uploaded lists. Mostly, users may accidentally enter invalid, inaccurate or non-existing email addresses that may not even reach the recipients’ inbox. This will certainly increase email bounce rates and returns a negative result to the mail server. Thus, there will be a dip in the reputation level of your email IP address and future emails will be flagged by the ISPs. Fortunately, the capability to verify and identify the full list of email addresses will prevent the probability of a failed delivery.
Email verification and validation include the 8 stage process to obtain a hygienic email list.
1. RFC Syntax Check
RFC Syntax Check verifies and validates whether the email address uses the correct RFC syntax format.
2. Domain Syntax Check
Analyses and validates whether the domain uses the standard syntax and authorises the top-level domain extensions.
3. Domain Validation Check
Domain Validation Check analyses the global DNS servers and confirms whether the domain name exists or not.
4. Mail Server Verification
Mail Server Verification verifies whether the domain identified in the email address has an active mail server to receive emails.
5. Role Email / Broadcast Email Flagging
Role emails and broadcast emails are those where multiple emails have a redirect receipt from a single role address. The email verifier will flag such addresses and decrease the chance of spam complaints and invalid email addresses in future.
6. Disposable Emails Flagging
Disposable emails are created by users who don’t wish to reveal their exact identity due to the fear of receiving spam mails.
7. Mailbox Existence Check
The mailbox check is done to ascertain whether the entered email addresses exist or not. It ensures a high accuracy rate in email addresses of catch-all domains.
8. Spam Reporter Score
A low, medium or high score is given to each email address based on the number of spam reported by the recipient in past. It helps to decide whether to include the recipient in a bulk campaign or not. If the recipient is not an opted member and has a medium or above score, then you can avoid sending your campaigns.
After all the above steps, marketers will acquire a valid, accurate and real email address list that has a nil chance to be marked as spam or bounced.
8. How do you implement email verification and data hygiene?
- Realtime Verifications
Realtime verification is where emails are verified at the point of collection. It may be at the web forms or other points of sales (POS). The best instance of realtime verification is the checkout page of an ecommerce shopping cart. Here, customers enter their email addresses and other information instantly to purchase something. Its implementation process includes the inclusion of the web services code into your system to alert the customer if they enter invalid details. It can be developed with the help of middleware services. Some companies verify the emails only before it is entered into the CRM or database.
- Benefits of Realtime Verifications
The biggest advantage of verifying the email addresses at the point of collection is that it alerts you of the invalid email address immediately. So your chance of sending to an invalid address is almost nil. Most of the invalid email addresses occur due to typo errors either manually or from the system. By using realtime email verifications, you increase the odds of fetching a new opportunity to grow a clean email list.
- Batch Verifications
30% of emails change every year, so you should clean them at regular intervals.
On the other hand, you can also verify email addresses in batches or bulk. Do you know that about 30% of emails change every year? You need to clean them from your database regularly depending on your business. cmercury uses the batch option for those who want to start with the verification process soon but have some technical restrictions. You can also initiate batch verification files and add realtime verification at the point of data collection, if possible.
9. How often should you use email verification and data hygiene tools?
This is one of the frequently asked questions in batch email verifications. As 30% of email addresses change annually, it is suggested to do database verifications on a monthly or quarterly basis for the best result. It also depends on your business model. A good strategy includes verifying those emails having a high engagement rate less often and verifying emails having a low engagement rate more often. If you want to reengage with old or inactive contacts in your database, that haven’t been emailed for over six months, then we strongly recommend performing batch email verifications before running any marketing campaigns.
