In this guide, we will share the best practices for collection of postal addresses, email addresses, and telephone numbers, to help ensure the quality of the information you collect.
Postal Addresses
A valid and accurate postal address will help ensure that physical mail is delivered accurately and on time. Here are some best practices to follow when collecting postal address data in your CRM:
- The correct format can vary depending on the country or region.
- Correct format: The correct format for a postal address typically includes the recipient’s name, street address, city, state or province, postal code, and country.
- Active address: The postal address must be an active and valid address, recognised by the local postal service.
- No blocks or restrictions: The postal address must not be blocked or restricted in any way that would prevent mail from being delivered to it.
- Delivery access: The postal address must be located in an area that is accessible to postal carriers and delivery services.
- Accurate information: The postal address must contain accurate and up-to-date information, such as the correct spelling of the recipient’s name and the correct postal code.

Emails:
Invalid or incorrectly formatted email addresses will result in messages not being delivered to the correct recipients. Here are some best practices for collecting accurate and valid email addresses:
- Correct format: The correct format for an email address is typically “username@domain.tld“, where “username” is the recipient’s email address, “domain” is the name of the recipient’s email provider, and “tld” is the top-level domain (such as .com, .org, .net, etc.).
- Active account: The recipient must have an active email account with the specified email provider.
- Correct spelling: The recipient’s email address must be spelled correctly in the “To” field of the email.
- Acceptable recipient: The recipient’s email server must be configured to accept email from the sender’s email server.
- Sender’s reputation: The sender’s email server must have a good reputation and not be marked as a source of spam or junk email.
- No filtering: The recipient’s email server must not have any filters in place that would block the email from being delivered.
Telephone Numbers
The correct formatting of a telephone number is essential for reaching the intended person and avoiding communication errors. Here are some best practices for collecting correctly formatting and valid telephone numbers:
- Correct format: The phone number must be in the correct format for the country in question, which typically includes the country code, area code, and local number.
- Active number: The phone number must be assigned to an active service, such as a landline or mobile phone, and be in service.
- No blocks or restrictions: The phone number must not be blocked or restricted in any way that would prevent it from being dialled.
- Coverage: The phone number must be in an area with coverage from the service provider, allowing it to be dialled and received.
