This is a tough one, and the truth is you're going to deal with a lot of rejections with any idea. Even with our newest product, which is generating 5-figures in MRR, we only heard responses from ~20% of people we outreached.

Here are a few tips to make it easier, that we've done ourselves:

1) Who are you talking to at the companies and unis? If you're cold outreaching to just random or general info@ or help@ email addresses, you'll likely to be ignored. Think about how many emails a company gets a day. How can you be different?

2) I'll typically use LinkedIn, or look at their website, and then use a tool like hunter.io to find the email address of the #2 or #3 in charge. I usually avoid the #1 because I assume everyone emails him, and the #2 and #3 are slightly more accessible.

3) When I do an outreach attempt, I try to make it slightly funny and different so it stands out. I also keep the sentences very short, and I don't use big words. This makes it MUCH easier for people to read if they're busy. If I don't hear back, I follow up two days later — and usually try with a simple video hello using the tool useloom.com.

No affiliation to any of the tools mentioned above, I just like them.

If you have any follow-up questions, feel free to reach out for a call. I've done a lot of outreach and sales to grow our products, and I've learned from some of the best sales people in the SaaS industry. Hope this helps!
