These services are used to perform the sending of emails when you run an email campaign and are used in conjunction with REC's Email Manager which is where you design and create the campaign and store the subscriber lists, plus track the open and click performance. Pricing and terms are also described there.

You can use an SMTP service or one of the integrated 3rd party email sending providers (ESP's): Mailgun & AWS. ESP's are for sending large volume campaigns and tend to be much faster than SMTP services and may offer other functionality and analytics. 


Contact us if you wish to use the AWS service.

Setting Up A Mailgun Account

  • Set up a mailgun account 

  • Add your site as a subdomain rather than using your main domain name such as your e.g.

    • NB this makes it disposable if a subdomain is banned for spam) 

    • NOTE: Do not use as this is usually already in use for your mailboxes.

  • Set up your DNS Records following the directions given on screen for TXT (SPF and DKIM) and MX but not CNAME (open/click tracking and unsubscribe is carried out in REC)

    • This might be on Cloudflare or via your own DNS provider. NB Cloudflare is typically within hours, other DNS providers could take 24-48 hours. 
    • Include the DNS records to send/receive and track email (if you are using Prospect Manager you can receive replies to quotes you have emailed out)

Example Cloudflare records

  • Validate your Mailgun account via the email confirmation and mobile number verification message
  • On the Domains tab, click to Validate Your Domain, Cloudflare is normally a matter of minutes, other DNS providers might be 24 - 48 hours.

  • Go to the Mailgun dashboard (click on the Mailgun logo) > click the subdomain you entered and get the API Key

  • Enter the keys in REC

  • NB Mailgun provides SPF and DKIM records which you can set up in your DNS to improve email deliverability


Setting up the email delivery service in REC:

  1. REC Admin > Integrations > SMTP Email Settings

  2. In the Email Driver drop down, select the service to be used:

    1. SMTP (generic SMTP service, typically slower than API-driven services)

    2. Mailgun (faster, paid 3rd party service with the option of timed emails)

  1. Set Enable These Email Settings to:

    1. Off - Use REC’s standard email system to send transaction and campaign emails

    2. All Emails - Send transactional and campaign emails through the selected email driver

    3. Email Manager Only - Use the selected email driver for email campaigns, REC will send transactional emails. Recommended in case your 3rd party service is suspended for sending out campaigns classed as being spammy.

  2. SMTP Config - enter your configuration details here.

  3. Mailgun API Config - enter your Mailgun configuration details here. NB “Subdomain” is the one used when setting up Mailgun e.g.

  4. Check / change the sending email address which will be used for the campaign in Site Settings > Company > Contact Email field. NB It might be possible to enter a specific campaign email address in the future.


Once you have completed your setup make sure to send test emails via your different contact forms, registrations and email manager to validate everything is working correctly. If available, login to your Mailgun / AWS accounts to see the statistics appear in there too.


Please ensure you only send out campaigns to clean email lists or your campaign will probably be suspended by the ESP.
