TL;DR / Quick Summary
Instantly charges $37 to $97/mo purely for cold email sending without built-in lead prospecting or spreadsheet BI. Olonyn provides complete custom SMTP email campaigns plus lead discovery, data cleaning, and proposal generation for $17/mo.
Why Cold Email Requires Built-in Lead Discovery
With Instantly, you must purchase a separate lead database tool (like Apollo) and export CSV files back and forth. Olonyn closes the loop by discovering verified leads and sending multi-touch email campaigns in the same dashboard.
Frequently Asked Questions
Does Olonyn support custom SMTP connections?
Yes! Connect Google Workspace, Outlook, Amazon SES, or private SMTP servers with AES-256 encryption.
