Inbox Zero vs Lavender

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.

Lavender coaches sales emails inside Gmail, Outlook, and sales engagement tools before you hit send. The Email Coach scores drafts against billions of analyzed messages, suggests personalization from prospect data, and rewrites weak lines so replies go up. A free Basic plan covers five analyzed and five personalized emails per month with no credit card.

Generic AI writers blast one prompt into every prospect. Lavender scores each draft in real time and ties coaching to your team's historic inbox data, which is why reply-rate lifts show up in case studies instead of vanity word counts. Ora, Lavender's newer AI sales agent, drafts outbound sequences on ora.im while the Coach stays in your inbox.

SDRs use Lavender to keep cold emails under 90-word coaching targets and book more meetings. Account executives personalize faster with the Personalization Assistant pulling context into Gmail or Outreach. Sales leaders track team email scores in the Coaching Dashboard instead of guessing from templates alone.

Basic stays free forever at $0 with five monthly analyses. Starter is $29 per month month-to-month or $27 on annual billing with unlimited emails and integrations. Individual Pro adds full integrations at $49 monthly ($45 annual), and Team plans start at $99 per seat monthly with analytics and coaching dashboards.
