Mailbell, a service of Limestone Labs LLC. Last updated June 25, 2026.
Mailbell sends you a short text message when a new email arrives in an inbox you connect by forwarding. We do not read, keep, or store the content of your emails. We read only the sender and subject for the brief moment it takes to build your alert, then discard it.
You must be at least 13 years old to use Mailbell. If you are under 18, you may use it only with the permission of a parent or guardian, who also consents to your receiving text messages.
By entering your mobile number and checking the consent box, you agree to receive recurring automated text alerts from Mailbell. Message frequency depends on your email. Message and data rates may apply. Reply STOP at any time to cancel, or HELP for help. Consent is not a condition of any purchase.
Mailbell may offer free and paid plans. Paid subscriptions are sold and billed through the Apple App Store or Google Play and renew automatically until canceled. You can manage or cancel in your app store account.
Use Mailbell only for your own inbox and your own mobile number. Do not use it to intercept someone else's mail without authorization or for any unlawful purpose.
Mailbell is provided as is. Forwarding and SMS delivery rely on third parties such as your email provider and mobile carriers and may be delayed or fail. We do not guarantee that every alert is delivered.
To the fullest extent permitted by law, Limestone Labs LLC is not liable for any missed, delayed, or undelivered alert, or for any indirect or consequential damages arising from your use of Mailbell.
You can stop at any time by turning off forwarding and replying STOP. We may suspend or end accounts that violate these terms.
We may update these terms from time to time. Continued use after a change means you accept the updated terms.
