Built for sales reps & SDRs

More meetings.
Less chasing.

Zinvite automates Outlook Web calendar invites at scale. Each one personalised, individually timed, sent from your own account — so it lands on the calendar, not in the inbox.

Reachoutly Benchmarks 2025
SDRs who add calendar invites to their outreach book 3–5× more pipeline than those relying on email replies alone.

The inbox is a waiting room. The calendar is a commitment. When you send a Zinvite, you’re not asking for attention — you’re claiming time.

How it works

From list to calendar
in under 5 minutes.

No coding, no CRM, no integrations. Zinvite runs on your Windows machine and drives your own Outlook Web session — nothing is shared with anyone.

01 — COMPOSE

Write your invite template

Add your subject line, body copy, date and meeting link. Or describe the meeting and let the built-in AI write a sharp template in seconds — using Claude, ChatGPT, or Gemini.

→
02 — LOAD

Paste your prospect list

Drop in emails in any format — comma-separated, one per line, or a CSV. Zinvite reads first names and companies automatically, so every invite feels personal with no extra prep.

→
03 — LAUNCH

Set your window. Walk away.

Pick your date and sending window (e.g. 9 AM–5 PM). Zinvite opens Outlook Web automatically and sends each invite at a different realistic time slot — nothing looks like a mass send.

What you get

Sends at volume.
Reads like one-to-one.

Unique time slot per recipient

Every invite lands at a different time within your chosen window. No two prospects receive the same slot — your outreach looks considered, not automated.

Every invite feels personal

Each invite is addressed by first name, with the company detected from their email domain. No mail merge setup, no extra CSV columns — it just works.

AI-written templates in seconds

Describe your meeting and the AI writes a sharp subject line and invite body instantly. Works with Claude, ChatGPT, and Gemini — use whichever API key you already have.

Retry failed sends instantly

Any invite that didn’t go through is flagged automatically. One click re-sends only the failed ones — no need to reload your list or start over.

Fully local — your data never leaves your machine

Zinvite runs entirely on your Windows computer through your own Outlook Web session at outlook.live.com. No cloud sync, no third-party server ever touches your contacts, your calendar, or your credentials. Templates, history, and settings are stored in a local file on your machine — yours alone.
