If you wish to disable password-protected downloads, you can do so by visiting your ZeroBounce profile settings.
Warning - It’s strongly advised not to disable password-protected downloads. This feature protects your sensitive data. ZeroBounce security measures ensure all users receive a unique, encrypted password when downloading email validation results from their accounts.
This is essential as it adds an additional layer of data protection in the event that your ZeroBounce account becomes compromised. While the attacker may be able to sign in to your account, they cannot view your contacts, email data, or results without the download password.
Removing this additional layer of protection leaves your sensitive data vulnerable if someone gains access to your sign in credentials. The attacker no longer needs a unique password to view your contacts or email addresses uploaded from your company’s database.
If you need to turn off password-protected downloads for any reason, follow these steps:


Check your email for the notification and click Approve Change to verify your request.


If you need to disable password-protected downloads, it’s recommended to re-enable the security feature at your earliest convenience. Your data privacy is essential, and ZeroBounce will always do everything possible to secure your account. Keeping password-protected downloads aids in this endeavor.
If you wish to re-enable password-protected downloads, you can visit your Profile settings and adjust the toggle again under Security Settings.

Verifying your email list at least once per quarter or every three months is recommended. Cleaning your list at this frequency is enough to help most businesses combat email decay while keeping up with their email list growth.
However, you may wish to verify your email list more frequently if you’re a larger business that regularly sees a high volume of new email leads.
In addition to these suggested time frames, reviewing key email marketing metrics is recommended regularly. Identifying and understanding problems in these areas can also indicate a need to clean your email list.
Internet and email service providers look for senders to maintain a 2-5% bounce rate. However, you must keep it at 2% or lower to protect your sender reputation.
Bounced emails are a telltale sign that some contacts on your email list are invalid. Verifying your email list will identify those outdated email addresses so that you can remove them from your list.
When someone reports your emails as spam or abuse, it increases your spam complaint rate. Internet service providers have a low tolerance for spam complaints and suggest that you keep it below 0.1% (1 in 1,000 emails sent).
If you notice a rise in spam complaints, it’s time to verify your email list. You’ll be able to identify problematic contacts on your email list, which we call abuse emails. These contacts are chronic complainers that misuse the report abuse function to your detriment.
Verifying your email list will help you spot them so you can purge them from your list.
Using an email verification APIⓘ is recommended to clean new email addresses at the time of registration. If you get a high volume of new email signups and are not using an API on your registration forms, you should clean those new emails in batches.
Alternatively, you can install the real-time email verification APIⓘ to your website, landing pages, and wherever you collect new email addresses.

Can I verify my emails in real time as they’re collected?
You can verify your emails as they’re collected in real time by using an email verification APIⓘ.
The API (Application Programming Interface) allows you to integrate your email verifier with your favorite platforms, websites, databases, or wherever you collect email addresses.
Verifying your emails in real time effectively lets you customize how you wish to clean your email list.
First - you’ll need to integrate your email verifier’s API code into your location of choice. A great place to install the real-time email verification APIⓘ is in your website’s account sign-up section.

Usually - users could enter any name or email address into the registration form. With the help of the real-time API, your email verifier will automatically detect invalid email addresses. Your visitors can only register for an account or mailing list once they provide a valid email address.
The real-time API is also helpful for detecting problematic, risky emails like abuse emails, spam traps, and disposable emailsⓘ. These email address types use a valid format but can damage your campaign performance and sender reputation. They can also put your email domain on a blacklist.
You’ll need two things to get started with a real-time email verification APIⓘ:
You’ll need to sign up for an account with an email verification service to obtain an API key if you don't have one. Some services allow you to create multiple API keys for different platforms.
Then, just add your API key to the appropriate field within the API code to verify emails in real time.
Free ZeroBounce accounts come with 100 credits. However, if you need to verify more emails in real time, you’ll need to add more credits to your ZeroBounce account.
For a more in-depth tutorial on setting up a real-time email verification APIⓘ, be sure to review our dedicated documentation.
Installing the API is simple and requires no coding expertise. However, if you prefer help and have questions about our API, contact the support team via phone or live chat, available 24/7.
