Waiting
One queue, an owner on every message and a clock on every reply
Mailslot sits on top of the addresses and channels you already use. This page follows one message from the moment it arrives to the Monday report.
Every channel lands in one queue
Customers keep writing to the address they know. Your team stops checking four places.
Gmail, Outlook or any IMAP mailbox. You keep your address and your history is imported.
Chat
A widget for your site that weighs 14 KB and loads after your page has finished.
Contact forms
Any form that can send an email or a webhook. Its fields become things a rule can read.
WhatsApp Business
On Team and Scale. WhatsApp’s own fee for each conversation is passed through at cost.
On Scale, every customer account has one named owner and a backup
Mailslot matches the sender’s domain to the account, so mail from anyone at that company reaches the same person. When the owner is off, the backup gets it and the reply says so.
A rule can match
The sender or their domain
Words in the subject or the message
The channel it came through
The time of day and day of the week
The customer’s plan or last order value, from Shopify or Stripe
Any field of a contact form
