Form notification emails from your website are sent from our email servers and Mandrill by MailChimp. The default mailserver is MailerQ, though if you would like to authenticate our servers, we will put you on Mandrill.
To ensure delivery of your email notifications, please read the following sections regarding Whitelisting and Authenticating.
If you are using email services with strong spam filters (Reflexion, Postini), we would recommend whitelisting our mailservers as approved senders:
- If your domain has no SPF record, please add the following TXT (SPF) record for yourdomain.com:
v=spf1 a mx include:_spf.prontomarketing.com ~all
- If your domain already have an exising SPF record, simply add "include:_spf.prontomarketing.com" before the ~all or ?all or -all arguments.
- TXT (DKIM) record for mandrill._domainkey.yourdomain.com:
v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCrLHiExVd55zd/IQ/J/mRwSRMAocV/hMB3jXwaHH36d9NaVynQFYV8NaWi69c1veUtRzGt7yAioXqLj7Z4TeEUoOLgrKsn8YnckGs9i3B3tVFB+Ch/4mPhXWiNfNdynHWBcPcbJ8kjEQ2U8y78dHZj1YeRXXVvWob2OaKynO8/lQIDAQAB;
Once you have added the two records, please let us know via a support ticket and we will switch the mailserver from ours to Mandrill.
If you need a list of IP ranges, you can get the most up-to-date data by running TXT command for spf.mandrillapp.com at sites such as MXToolBox.
Why authentication is important
Email servers are setup in a way that makes it very easy to send an email pretending to be someone else. This is a tactic called "spoofing" and it is often used by spammers. You may have seen this before with scam emails that look like they are coming from your bank. However, there are legitimate reasons to spoof an email address - most commonly with contact form notifications.
Email authentication is a technology that gives the recipient's mail server a way of checking the senders identity and confirm that the sender is actually who they say they are which improves security and deliver-ability.
