Email Service Providers (ESPs), like Gmail, Yahoo, and Outlook, use DKIM and SPF authentication as a way to filter incoming emails for spam addresses. Emails that fail authentication are more likely to end up in a spam or junk folder.
Setting up custom domain authentication is optional for Rare users, as the platform already handles both SPF and DKIM authentication on behalf of users.
However, you can choose to set up custom DKIM authentication for your domain and add Rare to your domain’s SPF record, which will have the following benefits:
- For some email clients, it may remove the default Rare authentication information "via raremail.io" that displays next to your Campaign’s “From” name.
- It can boost the odds that your Campaigns will arrive safely in your subscribers’ inboxes, rather than their spam or junk folders.
How to Setup Custom Authentication
To set up authentication, you need to change some DNS records with your domain host. Please contact our Support Team and they will provide you with the DNS records to enable custom DKIM & SPF authentication.
