Email address formatting recommendations for Engage Voice
Last updated on May 9, 2022
This article lays out email address formatting recommendations for the To, CC, BCC, and From fields in an Engage Voice email or email template.
While these recommendations will work for most major mail email clients and carriers, we recommend testing any atypically formatted email addresses before using them on the Engage platform.
Helpful hint!
RingCentral can only guarantee successful email transmissions if your emails are formatted according to these recommendations. Other formats supported by other mail clients or the email address RFC may work, but should be verified. RingCentral cannot guarantee that other email clients (recipients) will allow all email formats.
Email Address
A valid email address contains a personal_info section, followed by the ‘@’ symbol, followed by a domain. The personal_info section is subject to the following rules:
- Can contain a combination of uppercase and lowercase letters, digits (0-9), and special characters from the following set:
- ! # $ % & ' * + - / = ? ^ _ ` { | } ~
- Can contain a period (‘.’), provided that it is not the first or last character in the personal_info section, and that there are not two or more periods in a row.
The same rules apply to the domain section, with the exception that '.' (period) and '-'(dash) characters are the only special characters allowed.
In the To, CC, BCC and From fields, an email address may be enclosed by '<' and '>' characters.
Examples of valid email formatting
- someone@gmail.com
- someone.else@gmail.com
- Someone-Else@yahoo.com
- <someone-special@yahoo.com>
Email address with label
An email address may also be preceded by a display name, which may or may not include white space or double quotes. Valid examples include:
- label [valid email address]
- label<[valid email address]>
- label <[valid email address]>
- "label"[valid email address]
- "label" [valid email address]
- "label"<[valid email address]>
- "label" <[valid email address]>
- "some label"[valid email address]
- "some label" [valid email address]
- "some label"<[valid email address]>
- "some label" <[valid email address]>
- some label [valid email address]
- some label<[valid email address]>
- some label <[valid email address]>
Display names may contain:
- Uppercase and lowercase letters (A to Z and a to z)
- Digits (0-9)
- The special characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~
- A period (‘.’), provided that it is not the first or last character
- Space
- The double quote character (“), provided that it is included in a label that is already enclosed in quotes, and that it is preceded by the backslash ('\') character
- “ ( ) , : ; < > @ [ \ ] characters, provided they exist within a quoted string
Examples of valid label formatting
- Someone someone@gmail.com
- Someone else someone-else@gmail.com
- Someone else<someone-else@gmail.com>
- "Someone"someone@gmail.com
- "Someone-Else"<someone-else@gmail.com>
- "Some; \"Mail\" Box"<mailbox@office.com>
Multiple email addresses
The To, CC, and BCC fields within emails and email templates support the inclusion of multiple email addresses, so long as they are separated by a comma (,) or asemicolon (;), with space(s) before or after the commas/semicolons.
Examples
- someone@gmail.com,someone-else@gmail.com
- someone@gmail.com; someone-else@gmail.com, another-someone@gmail.com
- "Someone"<someone@gmail.com> ; someone else someone-else@gmail.com
