It's already one year. Wow. And until recently, my almost-free setup ran very staple. In short, Carrd, IFTTT, Google Sheets, Zapier, and Integromat powered everything.
But a couple of weeks ago, both Integromat and IFTTT made changes which made a switch to paid models necessary. So I had to decide to continue Trailerland or to pull the plug. After checking my options, I went with keeping the product alive. I found a way to move everything related to RSS and Twitter to IFTTT Pro.
Still not sure how to continue. Carrd and IFTTT Pro cost money. Not very much. I guess I spent more on beer ;) Maybe sometime I find another source of passive income to finance a paid Mailchimp account. This would open up the possibility for an additional audience for Trailerland, better control of #users and therefore the option for ads.
