Important Note: In April of 2022, Mailgun brought back the ability to implement 5 receiving routes on the foundation trial period which means you would be able to route all emails back to Highlevel! Back In January of 2020, Mailgun removed the ability to receive replies from their free tier. But now you can use Mailgun's 3-month free trial plan in order to receive emails in HighLevel.
There are two different ways to set up Mailgun
1. One Subdomain
You can set up one sub-domain in Mailgun for your marketing agency domain and use that same sub-domain for email sending across all of your client accounts in HighLevel
Pros:
- Easy setup - only need to setup one subdomain for your domain which you already have access to
- Emails are white labeled to your marketing agency domain
Cons:
If your domain gets disabled (gets a bad score due to bounce rates) email will stop working for all of your clients since all of their accounts are powered by the same domain.
The solution: don't send spammy emails to poor email addresses :-)
2. Multiple Subdomains
You can set up a subdomain in Mailgun for each of your client's domains and use that subdomain for sending for their specific HighLevel account. Once you set up a unique domain/subdomain for each location to capture cold inbound emails. Learn more about Cold Email Inbound Setup here.
Pros:
- Emails are white-labelled per the client domain
- If a client's domain gets disabled email only goes down for their client account
Cons:
Difficult setup - time-consuming having to set up a subdomain for all of your clients and getting access to each of their domains
