Q. Do you send an actual email out to each contact as
part of your checks?
NO, absolutely not! We never send an email.
Q. How do I know that my data is secure if I upload it
to your website?
We use highly secure servers in our data centre facility
based in London Docklands. This is one of the high-tech
centres of the world. Our systems are extremely secure
as we use network and database partitioning to ensure
all data is kept well away from web facing systems.
Protecting the privacy of your data is of paramount
importance to us. All your data is deleted as soon as
you finish using the service. Our reputation is worth
more than any single list - we are currently processing
over 1,000,000 emails per day for clients all over the
world!
Q. Can I contact you if I come across a problem?
YES, we are not a faceless Internet company. Customer
support is key to our service. Follow the “Contact” link at
the foot of the page to get in touch by email or phone.
Q. Who is the company behind EmailListCleaning.co.uk?
Our company Secure Email Hosting Ltd., registered in the
UK, was founded in early 2009. The founder, Jonathan
Rodger, has run several successful internet businesses
in the areas of secure online payments and email
marketing. See Jonathan’s public profile on LinkedIn.
Q. What format is the final cleaned list in?
We will provide the final cleaned list, plus a separate
list of failed addresses, in CSV (comma separated)
format. This can be imported directly into common
desktop applications such as Excel etc.
Q. What format do you require our data to be in?
Similarly, we require your lists in CSV format.
Q. How do you do the verification?
We use several layers of verification to clean your lists.
Please see a detailed explanation on how we verify emails.
Q. How accurate is the verification?
We typically achieve a 95% accuracy rate. There may be
some situations where the recipient’s ISP reports a
false positive (i.e. says the user exists but actually it does
not) but because we use several layers of verification we
are able to correctly determine the status of an email
address in the vast majority of cases.
Q. Can you detect where greylisting is used?
YES, we can usually tell if the email address has this
enabled, and will report back accordingly.
Q. How long does it take to clean my lists?
Because the service is automated, no human intervention
is required so the whole process is much faster than with
traditional list cleaning services. For lists under 100,000
the process take a couple of hours. For larger lists please allow
up to 12 hours. This is due to the time it takes to perform
the user verification with multiple ISPs.
