# Placeholders on Emails
## Overview
Rechat has the ability to send two kind of emails:
* Marketing Emails
* Transactional Emails
If you send a marketing email to 10 people, and use `Hi {{recipient.first_name}}` , each of the recipients will receive a personalized email with their name:
```
┌──────────────────┐ ┌──────────────────┐ ┌──────────────────┐
│ Hi Jane, │ │ Hi John, │ │ Hi Sarah, │
└──────────────────┘ └──────────────────┘ └──────────────────┘
↓ ↓ ↓
jane.doe@example.com john.doe@example.com sarah@example.com
```
However, when you send a transactional email, you are sending 1 single email, with the same copy, to 10 different email addresses. Email protocol doesn't allow one email, sent to different recipients, to have different content.
```
┌─────────────────────────────────┐
│ Hi Jane, │
└─────────────────────────────────┘
│
├──────→ jane.doe@example.com
├──────→ john.doe@example.com
└──────→ sarah@example.com
```
If we wanted to allow full placeholder capability on transactional emails, we essentially would've had to disable sending an email to multiple recipients (Multiple `to`, `cc`), because they all require the same email to be sent to multiple people.
#### How do I know what type of email I'm sending?
When sending your email, if you see the option to use `To` or `Cc`, that means it's going to be a transactional email.
Transactional email
However, if you don't have the option to use `Cc` and all recipients are `Locked in` as `bcc`, that effectively means you are sending a marketing email, which means we'll be sending multiple emails (one per recipient), but full placeholder functionality will work as expected.
Marketing email with only Bcc recipients.
