Inbox Zero

What is Inbox Zero?
Inbox Zero connects to Gmail or Outlook and uses AI to label incoming mail, draft replies in your voice, and surface what needs attention first. You get pre-written responses waiting when you open your inbox, plus bulk unsubscribe tools for newsletters you never read. The product works on web, iOS, Android, Slack, and Telegram so you can triage mail without living in your email tab.
Most email assistants stop at summarization. Inbox Zero also blocks cold emails, files attachments automatically on higher tiers, and pulls calendar and CRM context into drafts so scheduling replies match your real availability. The codebase is open source with 9k GitHub stars, SOC 2 Type 2 certification, and a self-host option for teams that want full control.
Starter plans cover solo operators who want labels, analytics, and reply drafts. Plus adds Slack, Notion, Stripe integrations, and an unlimited knowledge base. Professional adds team analytics and dedicated onboarding. Over 20,000 professionals use Inbox Zero, and every paid plan includes a 7-day free trial.
MailMentor

What is MailMentor?
MailMentor is an email assistant and prospecting tool built around a Chrome extension that scrapes contacts from news articles and company pages while you browse. It builds lead lists, exports them as CSV, and pushes leads through Zapier or webhooks when you want them in another CRM.
Traditional databases miss prospects buried in press releases or niche sites. MailMentor scans the page you are on, surfaces organizations and contacts other tools skip, then layers sequence building, Gmail outreach, and case-study insertion on paid tiers. Over 4,000 sellers use it according to the homepage, with Capterra reviews linked on the site.
Plans run from a free tier through $9 Prospect, $49 Outreach, and $79 Scale with up to 1,000 monthly contact scrapes. Sales reps mining news for leads, recruiters sourcing hiring companies, and founders doing outbound without a full SDR stack are the clearest fits.
