Reliable, Secure, Bullet Proof SMTP EMAIL DELIVERY 

Outstanding Service with Costs so Low there is No Reason to Manage your own SMTP Server! 

Emails get to the inbox when the Sender Reputation is high

The only way to GUARANTEE that you are building your own reputation is to use a dedicated IP to send your campaigns from a fully validated domain name

The Importance of a Dedicated IP

You can find other services that send bulk email using SMTP or Restful APIs using shared IPs and whilst this can work, you are never in control of your own sender reputation

  • With a dedicated IP, you have full control over your sending reputation. 
  • Your sending practices and reputation are not influenced by other senders sharing the same IP address. 
  • This control is especially crucial if you have strict deliverability requirements or send a large volume of emails.

We Know What Works

Email marketing is our business and we are passionate about making sure we are at the cutting edge using the latest technology so we can provide the very best inbox delivery

We have built a powerful SMTP sending engine from the ground up which is not built on old fashioned open-source technology found in services like Postfix or Sendmail

Our service is GDPR compliant, and we offer a range of services designed to get outstanding results for the lowest possible prices

We know providing a service that is plug and play simple and proven to work out of the box is critical because marketers want to focus on marketing not completing complicated SMTP server configurations and validating domain names

Once an order is confirmed, we provide instant access and connecting to any 3rd party email software takes minutes

Feature Highlights

  • We allocate a dedicated IP to every customer, if our autoresponder is connected, we create an individual IP warm up plan based on the list size of each customer, if a customer doesn’t have a list the warm up process is activated from new subscribers automatically
  • Domain validation is critically important and the system automatically issues and verifies a DKIM, SPF and a DMARC record which is essential to build a trusted sender reputation
  • We go the extra mile and create a custom reverse DNS record which ensures the IP resolves to the sending domain not a generic host name which is essential to protect the IP from possible blocks and blacklisting

Unique Features - Outstanding Performance

  • Dedicated IP or IP blocks based on sending volume
  • Individual Virtual MTAs
  • UK & North America Data Centres
  • Connect your email software in minutes
  • Automated Bounce Handling
  • Additional PAYG Email sending Credits
  • Premium Support

Key SMTP Features 

Dedicated IP
Each customer is allocated with a dedicated IP which is essential to build a trusted sender reputation, rather than sending from a shared IP 
IP Warm up

Essential to slowly introduce the new IP to the ISPs like Google, we create an individual warm up plan based on the list size of each customer

Domain Validation

System automatically issues and verifies a DKIM, SPF and a DMARC record which is essential to build a trusted sender reputation

Custom Reverse DNS

Reverse DNS is critical to stop spam and is increasingly being used by major ISPs to help verify email senders being identified as trusted senders

How it works

Each customer is assigned a dedicated IP or a block of IPs based on the sending volume which is critical for better inbox placement and provides maximum control

We configure the MTA to have its own delivery policy including unique IP, unique hostname, and individual domain settings such as simultaneous connections, messages, and intervals

IP Warm up Automation

It is essential for any new IP to be slowly introduced to the major ISPs

If our autoresponder app is connected, we provide a bespoke warm up schedule in our software and this is included in our comprehensive set up service to ensure your IP is ready to go

The key to our MTA engine is the receiving gateway sees the delivering virtual MTA instance as the source of the message, therefore if the IP of the MTA is not blacklisted the message will reach its destination and pass the domain reputation validations made through a reverse DNS look up

We are without doubt, the lowest priced bulk SMTP email host on the planet 

But we don’t compromise on the quality of our service

If you have been searching for a reliable SMTP service, you will see our prices below are significantly lower than any of our competitors

Wanted to post a review of the hosting service, i have the email marketing hosting and autoresponder and the delivery and performance is perfect, before i changed to the hosting I was using the autoresponder and another SMTP server but the delivery is now much better so all in all a great job plus I am paying half of what I was before.

Decided to go for the combined package because the cost is only a couple of pounds more than the SMTP Only plan, Set up was instant and I got access to my cPanel, connected the SMTP server to my autoresponder which took a couple of minutes and ready to go, the warm up plan that is also included was a big help and I am now getting really good delivery and open rates so very impressed

I have been using this SMTP service for the last two years and very happy,if i have any issues i always get a quick answer from support and that's all I ask

Got Questions? We got the answers!

Can I use my own email software?

Yes, the SMTP server is configured, and we validate the SPF, DKIM and DMARC records automatically, we provide the details required to connect to a 3rd party software in minutes.

Do I need to warm up the IP

Because we allocate new IP, we required a warm up plan to be activated prior to sending bulk email, this is to ensure we introduce the new IP to the major ISPs slowly so no red flags are raised and the IP blocked or blacklisted, if you use our own app, we include a warm up plan as part of our service, if you use a 3rd party software, we provide comprehensive guides in our admin area

What if I want to send more emails than the monthly allowance  

We provide a PAYG option to add more email sending credits to your account, if your business grows and you need more than the monthly allowance, you can either upgrade to a bigger plan or if it’s a one off requirement we provide PAYG credits for the additional emails sent

Can I use this service to send cold emails that have not provided permission?

No, if you send to recipients that have not provided permission, your IP will most likely get blocked and blacklisted, and the service may get suspended as with every other email sending service

Do you Guarantee email delivery?

No, email delivery depends on many factors, we set up your sending domain and validate the SPF, DKIM and DMARC records and allocate a dedicated IP, providing your list is permission based and you don’t send spam emails your emails will hit the inbox

Do you provide a refund period?

Yes, all our services are provided with a 14-day money back guarantee offer, this is for the hosting service but does not include any new domain registration so if you choose to register a new domain to use to host the account and decide to cancel the service, the domain registration provides 12 months service and is non-refundable.
