- 02Cold outreach
- 03Built-in anti-spam
- 04Campaign tracking
- 05Monitoring
Problem
Managers spend hours on manual client replies and cold outreach. Gmail isn't designed for bulk operations: no variable templates, no queues, no rate control. The result — slow, error-prone, spam-filtered, lost leads.
Audience
| Role | Scenario |
|---|---|
| Sales manager | Cold outreach with proposals to suppliers/clients with attachments |
| Account manager | Bulk replies to inbound inquiries using templates |
| Department head | Campaign control: how many sent, how many failed, success rate |
| Marketer | Launching outreach campaigns with company name personalization |
Primary profile — B2B companies with a steady stream of inbound inquiries and active outreach. No technical skills required: everything runs in the browser.
What's different
| Manual / Gmail | Agrovet Emailer |
|---|---|
| Copy-paste template into each email | Variable templates, batch sending |
| Forget rate limits — land in spam | Built-in delays and daily limits |
| No history: who got it, who didn't | Full tracking with retries (up to 3 attempts) |
| Attachments — manually per email | One file for the whole campaign, attached automatically |
| No CC — forward to colleagues manually | CC to team enabled with one toggle |
Unlike heavy platforms (Mailchimp, SendPulse) — works through your Gmail, no domain verification required, deploys in 10 minutes.
