There are a few things that can be done from your end which should help improve your mail delivery

By default there are no SSL certs associated with our hosting plans

To get a Free SSL cert for your website, go to https://www.cloudflare.com and sign up for a free account and complete the setup (this usually just involves changing the name servers for your domain name - it will not affect your website).  Then wait 24 hours and the SSL will be live on your website.  If you are using a CMS like wordpress or similar, then your will also need to update the site url, once the SSL is active - change to https://www.yourdomain

Once you have completed the cloudflare setup, go to the DNS section to make sure it has detected the mail settings. Check for the mail and ftp A records, if not listed then refer to the DNS records for your domain name at https://www.managethisdomain.com

v=spf1 include:secureserver.net exists:%{i}.mta.spf.extendcp.co.uk exists:%{i}.web.spf.extendcp.co.uk a:www.outitgoes.com –all

Then at the top of the page click on the link to add a DMARC record

Although adding an SPF & DMARC Record as mentioned above, you will achieve a better mail delivery score it is not a 100% guarantee your mail will arrive in their inbox.

Some other things to be aware of when sending mail:

Correct use of Capital Letters in the subject line is important and over use will make the email look like SPAM

1. In the content only use a max of one link and image where possible
2. Include a signature at the end of your email
3. Ideally include an unsubscribe link even if it goes to your email address
