Recipient

The recipient is the person or email address that receives an email message. The To and CC fields show who the message is addressed to, but delivery is governed by the SMTP envelope: the sending server names each recipient in a RCPT TO command, and the receiving server delivers to those addresses whatever the visible headers say. BCC recipients are usually not listed in the headers of the delivered message.

What does recipient mean in email?

The definition of an email recipient is the person who receives a message, as opposed to the sender who wrote and sent it. One email can have a single recipient or many, and each recipient address must be valid for the message to be delivered. If an address does not exist, the receiving server rejects it and the sender gets a hard bounce.

In email marketing, recipients are the people on your email list. They can be customers, trial users, or subscribers, and in most cases they should have opted in to hear from you.

To, CC, and BCC recipients

To. The primary recipients, the people the message is addressed to and who are expected to act on it.

CC. Carbon copy recipients get the same message for visibility. Every recipient can see who was copied.

BCC. Blind carbon copy recipients are hidden from everyone else on the message. BCC keeps addresses private, but it is the wrong tool for bulk mail: there is no per-recipient tracking, unsubscribe handling, or bounce processing. Marketing and product email should send each recipient an individual message through an email service provider instead.

Recipient vs subscriber vs contact

The three terms overlap but are not identical. A recipient is anyone who receives a given message. A subscriber is someone who asked to receive ongoing email, usually through a signup form or double opt-in. A contact is a stored record in your email platform, with properties like name, plan, and signup date. Every subscriber is a contact, and both become recipients the moment you send to them.

Why recipients matter in email marketing

Who you send to shapes your open rates, click-through rates, bounce rates, and sender reputation. Sending to invalid, unengaged, or non-consenting recipients raises bounces and spam complaints, which can hurt delivery for the rest of your list. Regular list hygiene and honest unsubscribe options keep your recipient base healthy.

How Loops handles recipients

Loops stores marketing and workflow recipients as contacts with properties and event history, so SaaS teams can segment by behavior and send marketing, product, and transactional email from one place. A transactional send goes to the address in the API request and adds the address to your audience only when addToAudience is true. Contacts who unsubscribe stop receiving marketing email while their subscription status is false. They can subscribe again later, and transactional email is unaffected.

FAQ

Who is the recipient of an email?
The recipient is the mailbox the message was delivered to. That address usually appears in the To or CC field, but BCC recipients do not appear in the delivered headers. If a message arrived in your inbox, you are one of its recipients.

Can an email have multiple recipients?
Yes. An email can list many addresses across To, CC, and BCC. For anything beyond a handful of people, send individual copies through an email platform instead of one shared message.

What is the difference between recipient and sender?
The sender is the party the message comes from, shown in the From field. The recipient is the mailbox it is delivered to. A message can have one recipient or many.

What does "recipient address rejected" mean?
The receiving server refused the address during the SMTP transaction. Check the status code in the bounce. A 5xx response reports a permanent failure for that attempt. Read the reason: an invalid mailbox should be suppressed, while an authentication or policy rejection may require fixing the sender’s setup. A 4xx response is temporary and may be retried.
