An updated email list is critical to a successful email campaign and realizing the return on investment. On average, email lists decline by 22.5% each year due to a natural subscriber attrition when people leave companies or change their personal email addresses. Email experts suggest that your lists need to be maintained regularly – in the absence of regular email list verifications, invalid/abandoned accounts will begin to accumulate in your database affecting sent messages to bounce back and your content not being read.
So – what can you do about it?
Verify your customer emails to achieve inbox delivery
We have released an email validation service to help businesses verify their subscriber lists. Using it is very simple: you just need to add email API to any forms where you collect customer data, from web forms to landing and contact pages to confirm emails in real-time without sending a message. This process acts as the first line of defense in ensuring accuracy for both new and existing email lists.
When you send an email campaign to thousands of email addresses, imagine how much a more accurate list will benefit your marketing program. Not to mention there are some additional benefits to the email validation service:
1. Maintain your IP/domain sending reputation
A sender score is like a credit score, it signals to email providers the trustworthiness of your outgoing emails. Sending to a bad email list will either force the emails to bounce or land in the spam folder. Most marketing experts agree that bounce rates shouldn’t be more than 3% to 5%. High bounce rates damage your sender score and send a red flag to Internet Service Providers (ISPs) about your mailing practices.
2. Protect against blacklisting
Invalid, broken, and misspelled email addresses lead to spam and ISP block issues. Our email validation service helps you avoid the case of recipients marking you as spam, which can contribute to your emails getting blocked in the future.
3. Uplift your revenue opportunity
A more accurate and verified list helps getting your emails to the right audience increasing your chances of converting users into paid customers. With any email campaign, segmenting and sending your content to the right audience ensures your content gets read and converts leading to a higher ROI on your efforts.
4. Reduce the cost of sending emails
Sending emails to invalid or non-existent accounts is money lost. Accurate lists that come with email list verifications help you get higher results from your email efforts.
5. Smart data insights
To harness the power of campaign insights starts with using quality data. Not only does it allow you to accurately profile your audience so your messaging is on point but gives you a more complete picture of how your campaigns perform over time so you can measure the direct impact on ROI.
Turn email addresses into sales opportunities
People mistype their email addresses all the time. For example, gmail.com can easily become gmal.com and it usually gets discovered when the email was undelivered. With our built-in suggestion service, we’ll return the email address with an invalid status and suggest a potential valid value instead.
Flag and remove suspicious emails
Your goal is to get emails delivered to real people, so you can build better engagement with your customers. Emails, such as help@, associate with a company, department or a group of recipients and not a real person. And disposable emails are temporary addresses known to be used by spammers. Our email verification API will identify invalid emails addresses you can remove them from your list. This will help reduce high bounce rates and SPAM complaints.
How can you start validating emails?
If you’re an existing Infobip Email user, you can contact your account manager to add email validation as a service. The service can be used over API or our Portal. The report results can then be downloaded as an .xls or text file formats. Invalid email addresses can be exported and removed directly from your own subscriber database. If you’re using our portal, all invalid emails can be uploaded to the blacklist service. The blacklist automatically filters bad addresses each time you want to send a campaign.
How email validation works using Infobip Portal
