The composer, and everything attached to the moment you hit send.
In this section
TemplatesA body written once, versioned, and sent many times: from the composer, from your own code, or by an agent.Send to an audienceOne email to everybody in an audience, a separate copy for each person, with their own name in it.FilesEvery attachment this mailbox holds, in one place you can search, download and clear out.Per-address email settingsEach address carries its own signature, footer and tracking. The catch-all covers what it catches, and one address’s choice copies to the rest in one step. Remote images and the blocklist can be set per address or per domain too.SignatureSeveral sign-offs on each address you send from, with one picked for each message.Writing toolsFormatting, inline completion and emoji shortcodes in the composer.Spelling and grammarSpelling, grammar and clarity suggestions as you write, checked on your own device.Send in theirsWrite in your own language and have it arrive in the recipient’s.Meetings & calendarA calendar at /mail/calendar in month, week and day views, holding both your meetings and the mail you have queued to go out later.DraftsAutosaved three seconds after you stop typing, and reopened from the Drafts folder with the recipients, the subject, the body and the From address intact. The attachments stay behind.Scheduled sendWrite it now, land it when they are awake.Remind me if nobody repliesSend a message and get it back at the top of the inbox if no reply has come by the time you pick.Undo sendA window to change your mind, and the composer comes back exactly as it was.See when mail you sent was openedWhether a message you sent has been opened, when, how many times and which of its links were followed. Off until you turn it on, and plain about the readings it cannot get.Tracking on your own domainTracked links and the open pixel on a subdomain you choose, such as links.yourdomain.com, instead of the Nextmail address.Files on your own domainDownload links for the files you send on a subdomain you choose, such as files.yourdomain.com, instead of the Nextmail address.AttachmentsPick them with the paperclip, paste them in or drop them anywhere on the composer. A pasted image lands in the body rather than the file list. On Nextmail mailboxes incoming files sit in object storage, one object each, and a file is fetched only when you open or download it.Checks before you sendYour draft scored for spam, phishing and AI writing as you write it, the way a receiving server would read it.Delivery statusWhich recipients a message you sent reached, and a warning in the list when one did not.Broadcast reportsEvery send to an audience on a page of its own, with delivery, opens, clicks, unsubscribes and each person’s copy.Sending analyticsWhat became of the mail you sent: delivered, bounced or reported as spam, by address and by how it was sent.Sending lanesApp mail and newsletters travel separately, so a newsletter never delays a password reset.Dedicated IPAn IP address that only your workspace sends from, as a paid add-on for high volume.AutomationsEmails that send themselves when someone joins a list or does something in your product.Booking pagesA link where people pick a free time and book a meeting on your calendar.
