# Best Practices to be Followed While Collecting User Emails

> Collect high-quality email addresses using double opt-in, explicit user consent, and organic sign-up methods to protect your domain reputation.

Collecting user email addresses properly is vital for successful marketing campaigns and maintaining a strong domain reputation. Unsecured or non-transparent collection practices can lead to poor quality data and frequent issues with your email campaigns. Follow these best practices to ensure your email lists are high-quality and compliant:

## Obtain Explicit Consent

Collect user emails from organic users who have **explicitly given consent**. The following are two methods to get consent from the users.

* * **Double opt-in method**: In this method, when a user signs up with your brand a verification email will be sent to them. After the user clicks on the verification link, you can send emails to them.
  * **Single opt-in with a Captcha**: In this method, the user is asked to re-enter the email address to avoid typos, also captcha prevents the bot signups. You can also integrate with a real-time list validation service to verify email at the sign-up page.

## Be Transparent and Set Clear Expectations

Inform your customers clearly when you collect their email addresses. Make sure they understand:

* The reason for collecting their email addresses
* What will you do with the collected data
* With whom will the data be shared
* The type of communication you send them and the frequency of engagement.

## Avoid Questionable Practices

* **Make sure not to auto-select** *Send me marketing/promotional/newsletters/etc* option when users need to input an email address for any transaction.
* **Do not purchase lists, scrape email addresses**, etc - i.e., do not send emails to people who have not explicitly consented to receive them.

## Comply with Data Privacy Laws

Make sure to **be compliant** with user collection or data privacy laws in your country. Some of the data privacy laws include:

* * U’s Digital Service Act (DSA) & Digital Market Act (DMA) from 2024
  * General Data Protection Regulation (GDPR, May 25, 2018)
  * California Consumer Privacy Act (CCPA, January 1, 2020)
  * Controlling the Assault of Non-Solicited Pornography And Marketing (CAN-SPAM, 2003)
  * Canada’s anti-spam legislation (CASL, 2014)
  * Vietnam updated its marketing and advertising laws on 15 September 2021
  * (Australia) Spam Act 2003
