Trusted Delivery from NewZapp

Trusted Delivery or MailChimp?

Mailchimp are the largest external email marketing provider for good reason, they provide a fantastic platform for sending volume email.

But are they the right fit for NHS internal communication emails? 


Choosing the right platform for your needs

Obvious spoiler alert – we believe it is Trusted Delivery! But your procurement policy will be looking for more than that when choosing your email delivery supplier.

There are two things you should demand from any provider. 


Your emails reach the inbox everytime.


Your data is secure and never at risk.

So why should you choose Trusted Delivery over Mailchimp when both look to meet these demands on the surface?

Email marketing providers send spoofed emails, always have, always will. They send your emails from their servers “pretending” to be you.

Blocking spoofed email is now a fundamental part of the NHSmail security policy. While once they would arrive in  junk folders or in the inbox with a click warning bar at the top, now they just get rejected entirely and don’t even make it to the recipient’s mailbox. 

As a result, Mailchimp will not be able to deliver emails at all. This is also true of other email providers as well.

NewZapp does not send spoofed email. We have worked with our existing NHS clients and NHS Digital to create Trusted Delivery.

Only one question. “Is the data stored safely in the UK?”

Trusted Delivery 1 – 0 Mailchimp

IT security has always been important for organisations but as we store more data about individuals and have many more access points to that data, the need for even stricter IT security has become inevitable for all organisations.

This is particularly evident within the NHS where the need to prevent computer viruses from entering the infrastructure is more important than ever.
