Everything You Need

A complete WhatsApp
outreach toolkit

From importing contacts to tracking delivery, LemonFlow handles the entire campaign lifecycle on your Windows desktop.

Excel & CSV Import

Drag in any Excel sheet or CSV — LemonFlow auto-extracts phone numbers including numbers with country codes, prefixes, and mixed formats.

Number Validation

Check every number on WhatsApp before sending. Skip invalid numbers automatically so your delivery rate stays high.

AI Message Composer

Write your message once and let AI improve the tone, fix grammar, and personalise it. Supports OpenAI, Gemini, and Claude.

Live Delivery Monitor

Watch messages go out in real time. See delivered, failed, and pending counts update live — with full pause, resume, and stop controls.

Campaign Scheduling

Schedule campaigns to fire at the right time. LemonFlow auto-restores scheduled jobs even if the app was closed and reopened.

Anti-Detection Technology

Randomised delay between messages (15–120s), typing simulation, and scroll simulation keep your account safe from WhatsApp bans.

Group Messaging

Send to WhatsApp groups you're a member of. Extract group member lists and run targeted group campaigns.

Reports & Export

Every campaign generates a detailed delivery report. Export to Excel for sharing or further analysis.

Media Attachments

Attach images, videos, and PDFs to your messages. Perfect for product catalogues, promotional banners, and invoices.

Simple Workflow

From contacts to delivered
in three steps

1

Import Contacts

Upload your Excel or CSV file. LemonFlow extracts phone numbers automatically. Validate all numbers against WhatsApp before you even compose a word.

2

Compose Message

Write your message in the rich editor. Add images or files, personalise with variables like name or city, and let AI refine the tone for better open rates.

3

Send & Track

Review the campaign summary and hit Send — or schedule it for later. Watch the live monitor as messages go out, then export the delivery report.

AI Message Composer

Write once. AI makes it convert.

Stop spending 30 minutes rewriting the same promotional message. Type a rough draft and let LemonFlow's AI improve it for WhatsApp — friendlier tone, right emoji, no grammar mistakes.

  • Supports OpenAI GPT-4, Google Gemini, and Claude
  • One-click "Improve" inside the message editor

Number Validation

Only send to real WhatsApp numbers.

Sending to invalid numbers wastes your quota and risks your account. LemonFlow checks every contact against WhatsApp before the campaign starts — so you only pay for messages that land.

  • Validates thousands of numbers in minutes
  • Skips invalid numbers automatically
  • Shows valid vs. invalid count before you send
  • Export the invalid list for CRM cleanup

FAQ

Common questions

Do I need the WhatsApp Business API to use LemonFlow?
No. LemonFlow works with your personal WhatsApp number or existing WhatsApp Business app account. It connects via a QR scan — no API subscription, no Meta Business approval needed.
Will my WhatsApp account get banned?
LemonFlow includes anti-detection features — randomised message delays, typing simulation, and scroll simulation — to mimic natural human behaviour. We recommend sending to opted-in contacts and keeping daily volumes reasonable. No tool can guarantee zero risk, but our approach is as safe as it gets for bulk sending.
Does LemonFlow work on Mac or Linux?
Currently LemonFlow is a Windows-only desktop app (Windows 10 and 11). Mac and Linux builds are on the roadmap.
Can I use LemonFlow on more than one computer?
Each license is bound to one machine. The Enterprise plan includes 3 device licenses. To transfer your license to a new machine, contact our support team.
How is the message quota counted?
Each message sent to one contact counts as 1 message. The quota resets on the 1st of every month. Validation checks do not count against your quota.
How do I get my license key after paying?
After payment, we issue your license key within a few hours via email or WhatsApp. Enter the key inside LemonFlow's onboarding screen and you're ready to go.
