I don't know one, but if you have Apple devices, Hide My Email may be a nice effort-free solution for you:

No one would dare block @icloud.com.

Also have you consider plus addresses or . addresses ("." is preferred if your email provider supports it -- harder to assume that you can just remove the dots for downstream spammers).

[EDIT] Did some quick searching, and the F/OSS community has delivered! There are at least two you could use:
