Terms
These terms cover why.email mailboxes, Why Mail, the apps that come with a mailbox (Calendar, Slate, Tabular, Chest, Nook, Townsquare and Porter) and the why.email developer API. By creating an account or using any of them, you agree to them.
[01]
Who you are agreeing with
why.email is run by Simplifyd Systems Limited (“we”). You can reach us at support@why.email. How we handle your data is described in the privacy policy.
[02]
Your account
- Give us accurate details, keep your password to yourself, and tell us if you think someone else has got into your account.
- You are responsible for what is done with your account, including by the apps and AI agents you connect to it.
- On a business account, the organization controls its mailboxes: its administrators can add and remove people, reset passwords and close mailboxes on its domains.
[03]
What you may not do
A mailbox is only useful while mail from it is trusted, so we are strict about this. You may not use why.email to:
- send spam, or bulk mail to people who did not ask for it, including through the developer API;
- send phishing, malware, or mail that pretends to come from someone it does not;
- harass people, or send or store anything that is illegal where you or the recipient are;
- probe, overload or get around the limits and protections of the service, or get into accounts that are not yours.
We may hold back mail, suspend sending, or suspend an account to stop abuse or protect the service and the people who use it. Where we can, we will tell you why and give you the chance to put it right.
[04]
Your content
Your mail, documents, files and messages are yours. You give us only the permission we need to store them, process them and show them to you and to the people you share them with, in order to run the service. That permission ends when you delete them, apart from copies in backups, which expire on their own schedule.
[05]
Plans and payment
- Business and developer plans are priced on the pricing and developer pricing pages, in naira.
- Paid plans are billed monthly, or yearly in advance, and renew until you cancel. You can move between plans at any time.
- If you cancel, you keep the paid plan until the end of the period you paid for, and then return to the free limits.
- Developer Pro sending past the included volume is taken from credit you top up in advance.
[06]
AI agents, Porter and other services
When you connect an AI agent to your mailbox, or connect services to Porter, the agent acts on your behalf within the reach and time you gave it, and you are responsible for what you let it do. Services you connect through Porter are provided by others under their own terms.
[07]
Townsquare
Townsquare is end-to-end encrypted and keeps your conversations only on your devices. If you lose every device you have signed in on, we cannot restore that history for you.
[08]
Availability
We work to keep why.email running and your mail backed up, and we monitor delivery and uptime. We cannot promise the service will never be interrupted, and we may change or retire features. If we retire something you rely on, we will tell you in advance and leave you time to take your data with you.
[09]
Closing an account
You can stop using why.email at any time and delete your accountyourself. It is deleted thirty days after you ask, and signing in before then keeps it. Because your mail is plain IMAP, you can copy it elsewhere first. A member of a business account is removed by the organization’s administrators, and an owner hands the organization to someone else, or is its last member, before deleting their own account. We may close an account that breaks these terms, or a free account that has not been used for a long time, after telling you.
[10]
Liability
The service is provided as it is. To the extent the law allows, we are not liable for indirect or consequential losses, or for lost profits, revenue or data, and our total liability to you is limited to the amount you paid us in the twelve months before the claim. Nothing in these terms limits liability that the law does not allow to be limited.
[11]
Changes to these terms
If we change these terms we will update the date at the top, and tell you by email before a change that affects your rights takes effect. If you do not agree with a change, you can close your account before it does.
