How does email authentication improve deliverability?
When you send an email it comes from two addresses, these are labelled the envelope and header addresses.
The header is your email address, which is visible to the recipient in their inbox. This email address will receive any replies sent by the recipient.
The envelope will be an address for your email marketing provider, this address is hidden in the message along with technical data such as IP address used and where to send bounce messages.
Spam & message filters look to block
spoofed or phishing emails Spoofing & Phishing email are attempts to trick you into giving out personal information such as your passwords and bank details.. They do this by checking if the domain owner (the header address) gives the sending server (the envelope address) permission to send emails on its behalf.
They are sent by spammers pretending to be an organisation or person you know, like a bank or family member, when in fact the true source of the email is them.
By having the correct
SPF, DKIM & DMARC SPF in place you authenticate the sending server in the eyes of the filter. Improving deliverability because your email marketing provider has permission to send emails on your behalf.
