Email Settings for GymMaster Online

Emails from GymMaster are sent through GymMaster's SMTP2GO account.

By default, they will be sent 'from' no-reply@gymmasteronline.com but with the 'reply-to' set to the sending email - club email address, or staff email address depending on the user.

Where a club or staff email address is set up correctly, GymMaster can send the email 'from' that email address domain eg. `hello@mygym.com`. This requires domain records to be set up correctly with your domain DNS provider, which is likely wherever the domain was registered. Adding and changing DNS records is usually pretty straight forward, but the process is often different between providers so some technical knowledge may be required.

Troubleshooting Page

There is a tool that will give you some details to copy and paste, and confirm things are set up right at https://yourgym.gymmasteronline.com/settings/email

The first time running the tool on a new domain will take a little longer. It can take a little while for changes to propagate around the Internet and we cache results for an hour, so the best approach is to run the check, make any required changes, then run the check again after a while.

Your domain name will need to have:

Valid Nameserver

We start by checking the domain name is in a valid format (eg. domain.com), registered, and has a nameserver (NS) record which tells the wider Internet who to ask for other records.

Valid SPF Record

When a mail server receives email saying it's 'from' a domain, it looks for a TXT record on that domain starting with v=spf1, which tells the mail server which IPs or hostnames are allowed to send from that domain.

We're specifically looking for include:spf.smtp2go.com, which lets the mail server know email sent from SMTP2GO servers is good to go, eg:

v=spf1 include:spf.smtp2go.com ~all
(Note you can only have one SPF record, so you may need to merge this into an existing record.)

Valid DMARC Record

A second TXT record starting with v=DMARC1; on the domain _dmarc.domain.com tells the receiving mail server what to do if the other checks fail. It needs to be one of:

• p=reject; (bounce the email)
• p=quarantine; (be suspicious of the email, eg. deliver but mark as spam)
• p=none; (accept the email anyway)

eg. v=DMARC1; p=none;

Valid and Verified DKIM Record

Email sent through SMTP2GO 'from' a verified sender will be signed by SMTP2GO. The receiving mail server then checks the domain's DKIM record to find out where it can verify the signature.

This requires two CNAME (alias) records added to the domain name, and are specific to your account so need to be taken from your troubleshooting page and will look like this with six numbers instead of `XXXXXX` (same numbers for each):

• sXXXXXX._domainkey.domain.com pointing to dkim.smtp2go.net
• emXXXXXX.domain.com pointing to return.smtp2go.net

Gmail and Yahoo Users

Gmail and Yahoo block sending of emails to their customers from 3rd parties using DMARC. This means that if you have a gmail address and try to send another gmail user an email, that email will not be delivered if the email was not sent through Gmail.

If you have an @gmail.com email address, you’ll need to have the From address as no-reply@gymmasteronline.com. This is because gmail will block anyone claiming to be sending emails as gmail as a fake person.

In this case, it can be easier to get your own business domain name and website if you don’t want to use gymmasteronline.com and gmail.com as your from address, with the additional benefit of personalized branding unique to your organisation.
