Could you reissue it with our new billing address? We moved to 14 Harbour Row in August.
All you need is your domain.
Real addresses for your whole team, on your own domain. Free.
- ada@yourcompany.comfounders
- tomi@yourcompany.comengineering
- support@yourcompany.comsupport
- billing@yourcompany.combilling
- anything-else@yourcompany.comgeneral
Any address at your domain works, even one you never set up.
01How it works
Three steps to team email.
- Add your domainPublish the DNS records Nexmail lists. It checks each one for you.
- Connect Resend or GmailConnect your free Resend account in one click, or add a Brevo key for sending. On Gmail or Workspace? Connect it with an app password and skip DNS.
- Invite your teamEveryone gets an address at your domain from day one.

02What it costs
Nothing, for a small team.
Higher volumes move you onto Resend’s or Brevo’s paid plans, billed by them. See pricing
- $0Nexmail
- Free for teams of up to 9 seats — people plus shared mailboxes.
- Free planResend
- Receives your mail through its inbound and sends your replies.
- Free planBrevo
- Sends your replies. It does not receive, so pair it with Resend’s inbound or your own mail server.
03Failover
Try to lose an email.
This is a working model of the Nexmail router. Switch both providers off and watch the lost count: mail waits in the queue, it never disappears.

- The router’s decisions appear here as they happen.
In the product a breaker stays open for five minutes; here, eight seconds. SMTP relay stands in for Brevo or any other provider you connect.

Nexmail makes sure every email to your domains is kept, reaches the person who owns it and gets an answer, even when a provider goes down at two in the morning.
04What it does
The life of an email, handled.
Six things happen to every message. Each one has a rule about what it may never do.
- 01ReceiveMail for your domains arrives through Resend or your own mail server.
- 02RouteEach address belongs to a Slack channel, set by rules you control.
- 03AnswerA shared inbox where the team assigns, labels, notes and replies.
- 04CheckEvery send is read for problems the recipient would see before it leaves.
- 05SendReplies go out through whichever provider is healthy, and wait when none is.
- 06LimitDaily ceilings and an emergency stop keep a mistake from becoming a flood.
05Routing
Every address has an owner.
Tell Nexmail which Slack channel owns billing@, careers@ or a whole domain. When no rule matches, the email is still stored and listed under Unrouted.
Northwind
In Nexmail: Unrouted 0
billing
Nothing here yet. Deliver an email that this channel owns.
06Shared inbox
One inbox for the whole team.
Every address lands in one inbox the whole team answers together. Assign, label, forward, leave private notes, start from a template and reply without leaving the keyboard: try j k x and Enter. Every send has a few seconds to undo.

07Pre-send checks
Stops the mistakes a customer would see.
A link that names one site and opens another, a program attached as a file, an address that unsubscribed: each one holds the send until you fix it. A loose DMARC policy is a warning and never blocks a reply.
- The link says one site and opens anotherThe text reads paypal.com, but it goes to paypa1-billing.co.
- Attachments are safe to openinvoice-2291.pdf
- Recipient has not opted outChecked against the suppression list.
- SPF and DKIM passnorthwind.co is authorised to send through Resend.
- DMARC policy is p=noneReceivers are not told to reject forgeries. Worth tightening; it never blocks a send.
08Calendar
Meetings land next to the mail.
Invites and meeting times in your email go on a calendar the team shares, synced with Google, Outlook and CalDAV. Share a booking link, send a notetaker to the call, and keep everyone you are selling to on a pipeline board with AI first drafts. See the calendar
- Team and personal calendars
- A Team calendar everyone shares, your own private one, and the calendars you already use. Google, Outlook, iCloud, Fastmail and any CalDAV server sync both ways; any calendar link (ICS) can be added read-only.
- Meetings straight from your email
- Invites, with their updates and cancellations, land on the calendar exactly. “Call on Thursday at 3pm” in an email becomes a tentative event, and each thread shows the meetings it set up.
- Quick add in plain words
- Type “Lunch with sam@acme.com Friday 1pm for an hour” and the event opens filled in for you to check. Nothing is saved until you do.
- Booking links
- Share a link and people pick a free time from your calendars. The booking lands on your calendar with an invite for both of you, a Google Meet link when it goes on a Google calendar, and a link to cancel.
- Meeting notetaker
- On the Team plan, send a notetaker to a Meet, Zoom or Teams call. The transcript and a summary land on the event, on the email thread and in its Slack thread.
