Receive SMS online for Fastmail verification – Virtual Number for SMS Verification
Fastmail sells email the way software used to be sold: you pay for it, and in exchange nobody reads your messages to sell you something. There are no adverts in the inbox, no tracking, and no AI scanning the contents. Mail, calendar, contacts and notes sit in one account, and the whole thing is built for people who spend real hours in their inbox rather than glancing at it.
The interface reflects that. The web client behaves like a desktop application, with keyboard shortcuts that let you clear a morning's mail without touching the mouse, folder rules you configure yourself, and a search that finds the message you half remember. The mobile app keeps the same shape, with swipe triage and notification controls that let you decide what is worth a buzz. Encryption protects data in transit and at rest, and the company operates under Australian privacy law, though it should be said that PGP does not run natively inside its own apps.
Masked Email is the feature people switch for. It generates a unique address for every service you sign up to, so the shop you bought a lamp from in 2023 holds an address that belongs to nothing else. If that address starts receiving spam, you know exactly who leaked it, and you can switch it off without touching your real mailbox. It plugs straight into 1Password and Bitwarden, creating the alias at the moment you fill in a signup form, which is what turns a good idea into a habit.
Opening the account itself confirms a phone number by SMS. Anyone attracted by Masked Email will recognise the logic here immediately, since the reasoning is identical one field down the form: an address for each service, and a number that is not the one your family calls. Take the confirmation on an additional number and it arrives inside your 5SIM order, while your mail, aliases and calendar stay in Fastmail.
How to buy a virtual phone number for Fastmail
Pick Fastmail from the service list on 5SIM. The countries currently holding numbers for it load next. Choose one and the operators serving that country and service pairing appear.
Every operator line carries price, available quantity and SMS delivery rate together. Weigh all three rather than sorting on price. Low stock behind a weak recent rate usually means a second attempt, which costs more than the cheaper line saved.
Your number lands in the active order as soon as you buy. Enter it in the Fastmail phone field, request the SMS, and the message arrives in that same order window. Orders stay live for roughly 15 to 20 minutes.
If nothing comes through, cancel the unused active order and the payment returns to your 5SIM balance right away. An unused order left to expire refunds on its own.
