What to look for in a great marketing startup
Specific wedge, not "all-in-one"
The best indie marketing tools nail one job — cold email, transactional email, SEO research, link tracking — better than the platforms.
Honest deliverability story
For email tools, deliverability is everything. Look for dedicated IP options, SPF/DKIM setup help, and transparent reputation tracking.
Sane pricing past the free tier
Send-volume and contact-count pricing can explode. Run the math on your actual list size and send frequency.
API quality
Marketers integrate everything. Check the docs — a great API is a multi-year retention signal.
Founder marketing in public
Marketing-tool founders who market in public know what they're selling. If the founder is invisible, the product likely is too.
