Protect Your Inbox with a Virtual Phone Number for Fastmail
Fastmail is a premium email service that prioritizes user privacy and security over data mining. To uphold its security standards and prevent spam, Fastmail requires a phone number for account verification. Using a temporary phone number aligns perfectly with Fastmail's privacy-first ethos and adds another layer of protection to your account.
Maximize Your Email Privacy
For a service dedicated to privacy, using a virtual phone number for registration is a natural fit. It allows you to create your Fastmail account without linking your primary phone number—a key piece of your personal identity—to your private inbox. This enhances your anonymity and ensures your email account remains a truly separate and secure communication channel.
Secure Your Digital Hub
Your email is the key to your entire digital life. Protecting it is paramount. Using a disposable phone number to receive your initial verification SMS from Fastmail strengthens your account's security from day one. It means that even if other personal information is compromised elsewhere, your email account is safer because your real phone number is not a known recovery vector.
A Clean, Ad-Free, and Private Experience
Fastmail promises an ad-free, private email experience. Using a virtual number helps uphold that promise by ensuring your phone number doesn't become a data point for any other service. It allows you to complete the necessary security step of verification while keeping your personal contact details completely out of the equation, leading to a truly private and secure inbox.
Frequently Asked Questions
Yes, our numbers are specifically designed for Fastmail registration. Fastmail requires a phone number for account creation, and our virtual numbers provide a reliable way to receive the SMS verification code.
Yes, you can. SMSFAST allows you to rent multiple virtual numbers, meaning you can use a unique number for each Fastmail account.
First, double-check that you've copied the SMS code precisely as it appeared in your SMSFAST account and entered it correctly into Fastmail. Also, ensure the number you used is still active and within its valid time frame.
If the issue persists, the number might have been flagged by Fastmail. In such cases, we recommend simply renting a new temporary phone number and repeating the registration process.
There may be a slight delay in network delivery at times. Please give it a minute or two.
- Request resend: On the Fastmail interface, look for the option to resend the code. This often prompts a new SMS message to be sent to your number.
- Ensure you are actively viewing the SMSFAST interface for the specific virtual number you rented, as the SMS message will appear there.
If the code still doesn't arrive after a resend attempt, the temporary number might be experiencing an issue with that specific service. We recommend canceling the current number (if no SMS has been received, you typically won't be charged) and renting a new disposable number from SMSFAST.
