## Inbox Zero

Inbox Zero is an AI executive assistant layered on top of Gmail and Outlook, built by developer Elie Steinbock (elie2222) and one of the most-starred open-source email projects on GitHub. Once you connect a Google or Microsoft account, it sorts incoming mail into smart categories such as To Reply, Newsletter, Marketing, Calendar, Cold Email and Notification, so you can triage by intent instead of scrolling chronologically. Every message that needs an answer arrives with a pre-written draft based on your past writing and your calendar availability, which you edit and send from the same view.

The tool is unusually broad for an email assistant. It blocks cold outreach before it reaches your inbox, shows you which senders you never open and lets you bulk-unsubscribe and archive them in a few clicks, and produces email analytics about who emails you most and what is clogging your inbox. Because it is open source and self-hostable, developers can inspect the code or run it on their own infrastructure — the company is SOC 2 Type 2 compliant and states your data is never used for AI training.

Inbox Zero also ships a dedicated email app for Gmail and Outlook across web, macOS, Windows and iPhone, is designed to be used from Slack, Telegram or Microsoft Teams, and offers AI meeting notes and pre-meeting briefings on higher tiers. The core app is free; the AI features are billed as a per-user subscription add-on.

**Pricing & Plans:** Freemium with a 7-day free trial on paid tiers. The email app is free; AI plans are billed per user per month (roughly $20 for Starter, $28 for Plus and $40 for Professional on annual billing, with monthly options costing about 20% more). Enterprise pricing with SSO, SCIM and on-premise deployment is available on request.

- **Automatic inbox labelling:** Incoming mail is sorted into categories like To Reply, Newsletter, Cold Email, Calendar and Notification as it arrives, using default rules or categories you define yourself.
- **Pre-drafted replies:** Emails that need a response get a draft written in your tone and referencing your real calendar availability and CRM context, ready to review and send.
- **Cold email blocking and bulk unsubscribe:** Stop cold outreach from ever reaching the inbox, see which newsletters you never read, then unsubscribe and archive them in bulk.
- **Email analytics:** Dashboards reveal who emails you most, which senders dominate your inbox and how your habits change over time so you can act on it.
- **Open source and self-hostable:** The full codebase is public under an open licence, so teams can audit, extend or self-host it, with SOC 2 Type 2 compliance and no AI training on your data.

**Strengths:** Genuinely open source and self-hostable, unlike most AI email assistants; Free core email app plus optional AI add-on keeps entry cost at zero; Combines triage, drafting, unsubscribe, cold-email blocking and analytics in one tool; Works across Slack, Telegram, Teams, web, desktop and mobile

**Limitations:** Best experience requires connecting Google or Microsoft account data; Free tier excludes most AI features, which need a paid per-user plan; Advanced tiers quickly get pricey for large teams

## Zenplan

Zenplan was created in 2024 by a founder frustrated with the opacity of wedding vendor pricing in Ontario. The platform gathers venue and vendor information — pricing, packages, and reviews — into searchable listings, then adds comparison tables so couples can evaluate several options side by side rather than chasing quotes by email. Categories currently covered include venues, photographers and videographers, DJs, and hair and makeup artists, with city-level pages for Toronto, Mississauga, Vaughan, Brampton, Hamilton, and Waterloo.

For couples, the core promise is transparency and organisation. Pricing details are collected from user-reported submissions and directly from vendors, so the numbers reflect what couples are actually paying. A centralized communication feature keeps messages with each vendor in one thread instead of scattered across inboxes, and filtering lets couples narrow results by date availability, budget, and service type.

On the vendor side, Zenplan works as a lead-generation and client-management channel. A paid membership gives vendors placement on the platform, instant notifications when a couple reaches out, and enriched enquiry detail such as the couple's date, venue, wedding theme, and which other vendors they've already booked. Vendors can also switch between the planning view and the business dashboard.

Because pricing for couples is not published as a fixed subscription, treat Zenplan as a free-to-explore platform whose monetisation comes from vendor memberships; contact the team for current terms.

**Pricing & Plans:** Access for couples is free to explore, with no published subscription — pricing details come from vendor and user-reported listings. Vendors pay for visibility through a Premium membership, advertised at roughly $2,000 per year with promotional free periods. Contact Zenplan for current plans.

- **Vendor search with smart filters:** Search venues, photographers, DJs, and beauty artists by category, city, price range, and availability so you only see options that fit your date and budget.
- **Transparent pricing listings:** Package prices are surfaced from user submissions and direct vendor uploads, so couples see realistic figures instead of having to request a quote for every enquiry.
- **Side-by-side comparison tables:** Line up multiple venues or vendors in one view to compare packages, inclusions, pricing, and ratings before committing.
- **Centralized vendor messaging:** Keep every conversation with every vendor in a single inbox so responses, quotes, and booking details never get lost in email threads.
- **Vendor lead inbox:** Partner vendors receive instant email notifications and detailed enquiry context — date, venue, theme, and vendors already booked — so they can reply with a tailored offer.

**Strengths:** Pricing is published up front rather than hidden behind a quote request; Comparison tables make shortlisting several venues or vendors fast; Centralised messaging keeps planning conversations organised; Vendor-side inbox delivers rich enquiry context, including date and vendors already booked

**Limitations:** Coverage is focused on Ontario, so it is not useful for weddings elsewhere; Vendor count per category and city is intentionally capped, which can limit choice; Consumer-side pricing plans are not published; you need to contact the team for specifics
