You'll need to add SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records and verify ownership of your sending domains before you can send email through your account. Retently is not able to send any email from unverified domains or domains without valid SPF and DKIM records, including public domains like gmail.com, yahoo.com, and more.

Although this seems too complicated for a non-technical person, the process is straightforward and is required to have your surveys delivered in the respondent Inbox.
To add the SPF and DKIM records for your sending domains, you'll need to add records of type TXT through your hosting provider, domain registrar, or DNS provider.
If you don't yet have an SPF record, add one for your domain, and make sure it's of type TXT. At a minimum, the value should be the following if you're only sending mail through Mandrill for that domain: v=spf1 include:spf.mandrillapp.com ?all.
If you already have a TXT record with SPF information, you'll need to add Mandrill's servers to that record by adding include:spf.mandrillapp.com in the record (before the last operator, which is usually ?all, ~all, or -all).
Add a new TXT record with the name mandrill._domainkey.yourdomain.com (just replace yourdomain.com with the domain or subdomain you're setting up).
The value for the record should be one of the options listed below. There are two options because the record contains semicolons, and 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
Here are links and information for several hosting and DNS providers.
Provider: CPanel (general)
Formatting Notes: DKIM record typically escaped automatically.
Many hosting providers offer CPanel to manage your domain. CPanel instructions are often similar among hosts that offer this option.
Formatting notes: The 'name' of your DKIMrecord should be mandrill._domainkey.yourdomain.com where yourdomain.com is replaced by the domain name where you're adding the record. Most hosts that utilize cPanel don't automatically add the domain name to the end of the record name.
Provider: DNS Made Easy

Formatting notes: The 'Value' field where you enter the content for each record must be enclosed in quotes.
Formatting notes: The 'data' field where you enter the value for each record must be enclosed in double quotes.

If your host or DNS provider doesn't appear here, contact their customer support or help files for more information. Each host may handle the adding or editing of records differently, so your host's technical support or documentation is the best resource for any limitations or formatting specific to that provider.
