Whenever you publish something online where you link to or mention others or their articles, products, resources, or companies, send them a quick email to let them know about your thing and nonchalantly encourage them to share it.
I do this all the time and it helps build relationships, drive shares, and can open doors for other things.
Since I do this so foten, I’ve wondered whether to build a Chrome extension to help do this job by letting you select the relevant links in your article, for which the extension would automatically dig up product/article titles, email addresses of those you should inform, and automatically composing and sending the emails for you. This is essentially what my VA does today for this kind of outreach, and it could be 90% automated. Let me know if such a tool would be of interest to you (just reply to this email)!
