Email Verification

Why use email verification?

Over 2 years development time has gone into our application to ensure that we can deliver the most reliable email verification within the market place. We have tailored the system to cope with the many vagaries of mail servers including grey-listing, false positives and velocity blocks.

FOR EMAIL MARKETERS

Significantly reduce the amount of bounces resulting from your email marketing campaigns.
Improve deliverability of valid emails and improve your sender reputation.
Reduce the chances of building up spam traps in your list.

FOR CALL CENTRES AND WEB CAPTURE FORMS

Use our API to validate emails at the point of capture from your website or call centre.
Ensure the integrity of your data.

FOR DATABASE MARKETING COMPANIES AND LIST BROKERS

Email databases decay at an alarming rate.
Make sure your clients receive the most accurate and clean data possible.
Remove hard bounces before the client sends their campaign.

HOW IT WORKS

EmailFlow’s email verification system is an online service, there is no software to
install. We run the checks from our own servers, so there is no risk of “blacklisting”
your own IP addresses.

Batch or Real-time verification

Our service can be used to upload bulk lists of email addresses, or as a web service for
real-time checking.

A simple process for you

We’ve done the hard work for you. All you need to do is upload your email list and wait
for the results to come in. We support batch files in CSV or TXT

WHAT DO WE CHECK

We do complete email verification including :-

Syntax – a simple check to ensure the email address conforms to RFC standards.
Domain – a lookup on the domain element of the email address to ensure it is
configured to accept emails.
User – the really clever bit, where we check that the user mailbox exists
(otherwise known as a SMTP check).

We never send email during our checks.

UNRIVALLED EXPERTISE

Over 2 years development time has gone into our application to ensure that we can deliver
the most reliable email verification on the planet. We have tailored the system to cope
with the many vagaries of mail servers including grey-listing, false positives and
velocity blocks.

To perform reliable email checking at the volumes we deliver is a very challenging task
requiring detailed knowledge of ISP behaviour and mail server technology. No other email
verification service can match the accuracy of our checks.

FAST CHECKING

We can check at rates over 100,000 emails per hour.

RELIABLE AND SECURE

Security of your data is our primary concern. To ensure security, we implement:

robust data security implemented using Microsoft Trustworthy Computing guidelines.
Logical security of your data by allocation of your own, dedicated database.
Any data that you upload goes into your database and is not visible by anyone else.
Physical security in secure US and UK data centers.

Once you delete a list from our system, it is wiped completely off our
servers. Ultimately, no one gets access to your data except you.

As well as the assurance of security, we appreciate that you want reliability. That’s why,
as a customer, you receive priority support by phone and email. In the unlikely event of a
technical problem, our promise to you is to resolve your issue within 24 hours.

Our systems include built in exception and error alerting. This means that, in the
unlikely event that you need to call us, we’ll already know about the problem and be well
on the way to fixing it.

Whether your requirement is a one-off list verification or ongoing regular use, we have a
plan to suit. With our batch verification plans, you have access to your own Dashboard to
upload lists and retrieve results. So get in touch today!
