By default, Lineup sends out all email communications from email@example.com. For enterprise customers, however, we offer the ability to send from your own domain (e.g. if you're with Acme Inc. and want to send emails from @acme.com, we can set that up for you).
Please note: currently, we support only a single, domain-specific email address to replace "firstname.lastname@example.org."
Setting this up requires some work on our end and collaboration with your IT team to configure our DNS for DKIM and SPF authentication (which is a fancy way of allowing us to send email on your behalf without it looking suspicious).
This documentation covers everything you need to know (or to pass on to your IT team) to get you up and running.
What Lineup needs to do
Step one is to let us know that you'd like to go down this route. There are some things that we'll need to configure with our mail service to add your domain as a sending domain. Reach out to your Lineup sales rep or create a ticket here to get started.
What the client needs to do
Set up DKIM authentication
To setup DKIM authentication, you will need to add a new TXT record with your DNS provider. The name should be
mandrill._domainkey.example.com (replace example.com with the domain you’re setting up).
The value for the record should be one of the options listed below—some DNS providers escape semicolons for you, while others require you to do it when setting up the record.
With semicolons escaped:
v=DKIM1\; k=rsa\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB\;
With semicolons unescaped:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
To enable SPF, add another TXT record, this time for the bare domain you added as your sending domain. The value should be, at minimum:
v=spf1 include:spf.mandrillapp.com ?all
If you already have a TXT record with SPF information, you’ll need to add Lineup's servers to that record by adding
include:spf.mandrillapp.com in the record (before the last operator, which is usually
There's one more TXT record that you'll need to create in your domain's DNS records. This value is different for each domain, and you'll need to reach out to Lineup Support if we have no already received it.
It begins to
mandrill_verify and ends with some random numbers and letters.
Contact Lineup Support
Once you have configured all three TXT files, please reach out to Lineup support again. We'll verify that the SPF and DKIM settings are valid and your domain is verified, and you should be all set.
Select an email address
Currently, we can support a single, domain-specific email address (we have plans to update this later on). Please include in your final support ticket the email address that you would like all of your emails to be sent from. We recommend setting up a shared mailbox on your domain to handle this.
