When you send emails from Envoke - or any other email provider - your messages need to be authenticated to ensure that spam and malware filters on the recipient side can confirm that your messages and identity aren't forged. 

DomainKeys Identified Mail (DKIM) is an email authentication method that is used to verify the identity of the email sender and detect forged email addresses, which is a technique often used in phishing and email spam. 

There is no extra fee for DKIM setup, it is included with every billing plan.

DKIM works in the background. There is no change in the way you use Envoke. It is setup on the domain level by the person/department that manages your domain name. Once setup, it allows spam and malware filters to authenticate your emails; to confirm that they are coming from you and not by someone else claiming to be you. This in turn, increases inbox delivery. Spam filters trust DKIM and as such fewer emails are filtered out as suspicious.

Envoke provides default DKIM authentication with each outgoing email, but in some cases this isn't sufficient to satisfy email filters and custom authentication is needed for the sending domain.

Custom DKIM setup works especially well for internal messages where the sender email address and the recipient email address is from the same domain, for example from jack@yoursite.com to jill@yoursite.com

Follow the on-screen instructions from the Account Settings page.

Step 1: Enter the domain name that you wish to authenticate to send emails from. This is the domain after the @ symbol in your email address. For example if you plan to send emails from info@acme-inc.com then the domain is acme-inc.com.

Step 2: After you enter the domain name a code will be generated. Send this code to your internal IT to add to your domain's DNS record, which is managed by your domain's registrar.

Step 3: Click the Verify button to confirm setup is done correctly. Once verified, no further action is needed. If verification fails, you need to ask your IT person or team to review the setup.

When a domain is verified you can send emails from any email address from that domain. For example if you verify acme-inc.com you can send emails from anything@acme-inc.com

Note that Envoke support does not get involved with DKIM setup with your domain registrar, you need to contact your domain registrar, such as Godaddy, for help. Tip: Search in Google for "How do i add DKIM record in REGISTRAR NAME"
