Email and deliverability : definitions and examples

A/B Testing

An AB Testing campaign allows you to test one of your campaign’s attributes
  • subject line
  • sender
  • content (title, tagline, etc.)
  • call-to-action (CTA) button.
This test is sent to at least two sample email addresses. The aim is to determine which version (A or B) gets the best results. This enables us to send the best-performing version to the rest of the audience.

Email address

The email address is a unique address that allows people to be contacted online. It is regulated by rules that restrict its naming. scheme_maximum_size_email_address_mindbaz

Apple Mail Privacy Protection (Apple MPP)

BIMI

BIMI stands for “Brand Indicators for Message Identification”. It’s a new standard that makes it easier to identify the sender of an e-mail. BIMI is linked to the sender. If a brand has a BIMI registration, it enjoys several benefits from Mailbox Service Providers who have implemented BIMI:
  • Display its logo in mailboxes supporting BIMI
  • Immediate email sender identification
  • For users, it’s an additional security feature

Inactive contact

An inactive contact is a contact that does not interact or no longer interacts with sent content.  A contact can be inactive in different ways: 
  • Inactive addresses: These contacts have never interacted with your e-mails since signing up. 
  • Formerly active contacts: These contacts used to open and click on your e-mails, but no longer do so. 
A contact can be active for one sender and inactive for another. 

Deliverability

Email deliverability refers to the ability of a message or campaign to reach its recipients in their primary or secondary inboxes (e.g. Google’s promotion tab).  

Display Name

The sender name, or Display Name, is the name that appears in your recipient’s mailbox instead of your sender email. By following the best practices of MSPs and filters, the formatting of this Display Name will have a positive impact on your deliverability.

Disposable Email

It’s an email address that allows you to receive emails at a temporary address. The email address is self-destructing or reset after a given period of time. These services, created for private individuals, make it possible to avoid giving out a personal email address and therefore receiving spam.  Some disposable email creation services give access to the inbox linked to the email address during its lifetime. This feature is helpful for validating confirmation emails when creating an account. In France, two well-known temporary e-mail services are yopmail and temp-mail.  

Hard bounce

A hard bounce is a hard error message returned by the Mailbox Service Provider. It indicates that the requested user does not exist (or no longer exists) due to an invalid or outdated e-mail address. Hard bounce examples:  camille@travol.com > domain error firstnameexemple@yahoo.com > address no longer valid.  

Opt-in

Before you can send communications or advertising by email, text message or MMS, you need to get the recipient’s consent. A recipient is said to be opt-in if they have agreed to receive messages from a company. An opt-in database is made up solely of contacts who have given their consent to receive messages.  

Email router

An email router (or ESP) allows you to manage the sending of email messages to a large list of recipients. Most email routers include in their services: 
  • SPF and DKIM declaration management 
  • IPS preheating 
  • An interface for monitoring statistics and adapting email lists.
 

Soft bounces

A soft bounce is a temporary error message. Examples include:
  • a full mailbox
