How to Get My First Free Users/Testers for a Blogging Automation SaaS? (I will not promote)

Hey everyone, I’m launching a SaaS product, which automates blog posting for WordPress sites. It analyzes past content, generates SEO-optimized posts in a matching style, and schedules them automatically. It’s aimed at bloggers who want a ‘set-and-forget’ solution to keep their blogs updated. I’m looking for ways to get my first free users or beta testers to provide feedback. I’m curious how long this might take and if there are any specific tactics or strategies you’ve found successful for getting early users for a SaaS. I’ve considered: • Reaching out to blogging communities • Approaching inactive blog owners But I’d love to hear from others who have launched SaaS products—what worked best for you? Any specific tactics, communities, or outreach methods you recommend? How long did it take you to get those first few users?
