Esboces email header

Here is an example of an email header for an email sent from an ESP (Email Service Provider) like Mailchimp, Constant Contact, or Klaviyo:

From: [Your Company Name] [Your Company Email] [Your Company Phone Number]
Reply-To: [Your Company Email]
Subject: [Subject Line]
Date: [Date]
To: [Recipient Email]
MIME-Version: 1.0
Content-Type: text/html; charset=UTF-8
X-Mailer: [ESP Name] (v[ESP Version])
X-Priority: 3
X-Mailer-Info: [ESP Name] (v[ESP Version])

Here's a breakdown of each field:

• From: The sender's name and email address.
• Reply-To: The email address that will receive replies to the email.
• Subject: The subject line of the email.
• Date: The date and time the email was sent.
• To: The recipient's email address.
• MIME-Version: The version of the MIME (Multipurpose Internet Mail Extensions) standard used to format the email.
• Content-Type: The type of content in the email (in this case, HTML).
• X-Mailer: The name and version of the ESP used to send the email.
• X-Priority: The priority level of the email (in this case, normal).
• X-Mailer-Info: Additional information about the ESP and the email.

Note that not all ESPs may include all of these fields in their email headers, and some may include additional fields specific to their platform.
