I subscribed to this email reminder by the Almanac and it's WONDERFUL! I'm so busy and scatterbrained that I invariably get things started too late so hopefully this year they will keep me on track. I don't think they
sell their email list because I haven't been bombarded with other solicitations.
Tailored to your zip code, they send periodic emails (monthly I think) to remind what needs to be, or can be done, in the near future. You put in your zip code and it provides real-time projected frost dates, frost and moon seed starting dates for indoors and out, xplant dates, etc.
Here's a sample of what I just received:
