As a user of Loxo's emailing features, we recommend updating your DNS settings to authenticate Loxo's domain to increase your email delivery rate and to ensure your email address does not get flagged for sending mass emails.

Your personal or work email account is not designed to send a high volume of emails without the risk of your provider marking them as spam or junk. Loxo's server was built for high volume emailing and can significantly reduce the risk of your emails being flagged. To use Loxo's server, simply select "Loxo" under the Send as... option for your bulk email or campaign.

How to Set Up Your Domain

Setting up your email domain to have the ability to send through Loxo's servers can help increase your sending ability greatly! This in turn helps users avoid things like throttling errors when emailing in bulk, and this ultimately can assist in maintaining a better domain reputation. Maintaining a good domain reputation is crucial in staying out of the spam folder. **It is important to note that sending via Loxo isn't a sure way to avoid hitting spam. Being marked as spam ultimately is determined by your domain's reputation and the recipients email server settings.**

Setting it up is a matter of adding a few TXT records in your domain registrar and usually goes pretty quick once you know where to make the change. Each domain registrar has its own website and interface to allow you to manage this information, but the actual records that need to change are the same.

Accessing the records from Loxo

  1. Navigate to Initials in Bottom Left > Settings > Loxo Email Domains

  2. Click on Show DNS Records for

3. Use the generated fields to enter in two TXT and a CNAME field in your domain host.

4. If you have an IT team, share these records with them and they can update this for you.

Finding your Domain Host

1. Login to your Domain host. If you don't know where it's hosted you can use the below steps to find where your DNS is hosted:

  • Go to

  • Enter your domain.

  • Look for the "Your email service provider is" line. The domain will be listed there.

Adding Records to your Domain

1. Login to your Domain Host and look for where you can update or manage your DNS settings (common domain hosts examples and instructions listed at the end of this article!)

2. Update or add an SPF record.

  • A domain can only have one SPF record, if one already exists you must combine the current record with the Loxo record.

  • Search for "v=spf1", if there are multiple pages, ensure all pages are searched.

  • If a SPF record exists then add to the record. For example, if your record is v=spf1 ~all, the final record should be v=spf1 ~all

  • If a SPF record doesn't already exists then add a brand new TXT record with the value: v=spf1 ~all. The hostname will either be "@", your domain, or left blank depending on the registrar.

3. Add the DKIM key:

  • Add a new TXT type record.

  • The hostname will be loxo._domainkey

  • Copy the value from the spreadsheet support provided you. It will start with k=rsa

4. Add the CNAME record:

  • While this is optional it is strongly recommended for open, click, and unsubscribe tracking.

  • Create a new CNAME type record.

  • The hostname will be loxo-email

  • The value will be

5. Reach out to support again letting us know you made these updates and we can verify on our end that everything was set up correctly!
