I'm going to give you advice that's contrarian to what you'll find online. Why? Because most advice out there I've noticed is by people who haven't actually done it.

These strategies worked for our business to generate real, actual revenue for selling a digital product — and it's inexpensive to start.

1) Outreach to friends — with a catch. Everyone has heard the advice that you should email your friends who are interested. I think that's true, and we've closed roughly 20% of our friends who we emailed about our product (or texted). But even for those friends who aren't interested, a good trick is to say "I know you're not interested, but who's one more person who might be? I'm happy to give you an affiliate commission if you refer someone." Because digital products are so inexpensive to produce, you could give $5 to a friend for referring someone because the margins on the sale are typically so great.

2) Partner giveaways. Giveaways still work well. We have a sister company that generates five-figures in net new revenue each month from giveaways. Their secret is partnering with other companies. Use a tool like BuzzSumo (or just Google) to find products in your niche. And then use a free giveaway tool (disclosure: my company makes one, but I don't want this post to be biased so I won't name it... just Google and use whatever you want). You want to aim for 3-5 partners. Just reach out and ask for a free product, in exchange for linking to them and mentioning them on the giveaway page/your promotion emails. That's typically good enough. You will fail with people who turn you down, but the benefit is partners will help you cross-promote which give you 2-5x the number of entrants. You can then promote your product to all your new email subscribers.

Good luck! I hope this helps.
