Leaving something?
Here is what changes.
Presend is a send gate, not a suite. Each page below says what the other tool does well, what Presend does instead, and who should stay where they are. The ❌s in our column are real.
Tessian alternative for teams without a security department
Tessian stops misdirected email with behavioural analysis, sold through Proofpoint on enterprise terms. Presend does the pre-send check per person, in 30 seconds, for $3 a month — and is honest about what it does not do.
CompareEgress Prevent alternative that a team can install itself
Egress Prevent, now sold by KnowBe4, catches misaddressed email and attachments at the mail server on enterprise terms. Presend catches secrets, PII, banned phrases and AI slop in the compose box, per person, for $3 a month.
CompareSafeSend alternative that works outside Outlook
SafeSend pops a confirmation in Outlook when you email an external address. Presend does that in Gmail and Outlook Web, adds nine more checks, runs in Slack and LinkedIn too, and lets you write your own rules — but does not cover the Outlook desktop app.
ComparePurview and Google Workspace DLP alternative for people without an IT department
Built-in DLP in Microsoft 365 and Google Workspace is powerful, admin-only, and gated behind the expensive editions. Presend gives each person the pre-send check in the compose box — in Gmail, Outlook Web, Slack and LinkedIn — for $3 a month.
CompareZivver alternative for teams that need a check before send, not secure email
Zivver encrypts sensitive email and warns about wrong recipients, sold per organisation to healthcare, government and legal teams. Presend checks every message each person sends, for $3 a month, and does not encrypt anything.
CompareSuperhuman alternative if you are leaving over the bundle, not the speed
Superhuman Mail now comes only inside the $33-a-month Business bundle with Grammarly and Coda. Presend is not an email client. It is the one thing Superhuman does not do — a send gate — inside the Gmail or Outlook you already have, for $3.
CompareShortwave alternative if you want the AI check without replacing Gmail
Shortwave replaces Gmail with an AI-first client from $24 a seat. Presend stays inside Gmail and checks what you send — secrets, missing attachments, AI slop, your own rules — for $3. It does not summarise, search or triage; that is the point.
CompareNot on the list?
Presend runs alongside almost anything, because it only touches the message you are about to send. Install it and keep what you have.
