It’s Time for Spring Cleaning with Bulk Email Address Validation 

Spring has arrived, and that means it’s time to start fresh and begin spring cleaning. That could mean getting rid of old shoes, refreshing your wardrobe, or finally donating that one shirt you thought you would wear this year—yet again you haven’t.

What does email have to do with spring cleaning? You can think of Bulk Email Address Validation like spring cleaning for your email list. When you declutter and organize your home during a seasonal refresh, you feel better removing items that are no longer of significant value or use.

Bulk Email Address Validation allows businesses to clean up and organize their email lists by removing invalid, outdated, and inactive email addresses to have better deliverability to inboxes.

What’s new?

Twilio SendGrid is introducing Bulk Email Address Validation as a way to better maintain list hygiene, improve deliverability at scale and ensure emails are reaching the intended audience. SendGrid’s Real Time Email Address Validation has been supporting customers with use cases such as validating signup emails since 2019. Bulk Email Address Validation expands on this offering by supporting customers managing large existing email lists for a variety of use cases.

Common use cases

New customer list cleaning

Customers joining SendGrid will have a large amount of email addresses stored that could benefit from the validation APIs. When ramping up your email traffic with a new provider, it’s important to be particularly cautious of bounces. Bulk Email Address Validation is a valuable component to making this process seamless. Additionally if customers have clients with their own marketing lists, email address validation is great for onboarding them onto a new platform. 

High bounce rates

High hard bounce rates are a direct indicator that the emails in their lists are invalid or non-existent. The result can negatively impact sender reputation and cause legitimate email to be sent to spam. Bulk Email Address Validation can be a great first step to lowering bounces if it’s otherwise difficult to identify the source of these issues.

Updating customer bases

When customers need to send a Terms of Services update or marketing push to an entire user base, they will be contacting a much larger audience than normal . Inboxes are more responsive to these changes in behavior, which can lead to high bounce rates and spam reports. Removing Invalid or outdated email addresses from this list prior to sending will result in better deliverability. Any large scale increase in mailing volume will benefit from Bulk Email Address Validation.

How Bulk Email Address Validation works

Bulk Email Address Validation allows you to check the validity of up to 1 million email addresses at one time.  It provides a scalable  way for customers to identify how likely an email address is to receive email. Simply uploading a CSV list of email addresses, and the Bulk Email Address Validation API will return a “Valid”, ”Risky” or “Invalid,” a percent likelihood that the address is valid, as well as the reasons that factor into the decision. Different from the Real Time Email Address Validation that currently exists, Bulk Email Address Validation can process large scale email lists 50x faster.

Maintain list hygiene

Bulk Email Address Validation handles email list hygiene before sending to your customers. One of the first indicators inbox providers, like Gmail and Yahoo!, check when considering inbox vs. spam folder placement is whether companies are sending to real email addresses. They want to know that real people are signing up to receive your emails. If you send to email addresses that don’t exist or haven’t engaged in any email in a long time, it’s a good indicator to inbox providers that your email address collection practices aren’t cleaned up. This can impact your sender reputation and get your emails stuck in the spam folder

Reach the intended audience

Bulk Email Address Validation is a tool that flags bad addresses in your current email lists, double checks whether email addresses in your mailing list are going to real inboxes and supports onboarding new clients with their own marketing lists. Ensuring emails are sent to the right inbox helps improve reputation, decrease bounce rates and improve sender reputation. 

By reaching your intended audience, you can increase your engagement rates since you are more likely to connect with individuals that are genuinely interested in your content or offerings. 

Deliverability at scale

Email deliverability can be an incredibly opaque system and it can be difficult to know exactly why you’re not getting engagement or if you’re even reaching out to real people. Spring cleaning isn’t the only time to clean your list, we also recommend maintaining list hygiene if you're working with a large email list. It can be challenging to ensure that every email address is valid and active.

Bulk Email Address Validation solves this problem by identifying and removing invalid or non-existent email addresses to improve deliverability. Bulk Email Address Validation is built for scale, so you don’t have to worry about cleaning one email at a time. Twilio SendGrid provides the resources to clean your large email list, all in one go.
