I have installed a newsletter plugin on my WordPress website. I picked Hubspot as it seems to have good reviews. It allows anyone visiting my site to sign up to receive any newsletters that I have the urge to send out.
Newsletters about what, I hear you ask? Probably about any book launches, audiobook work, possibly even a particularly successful reorganisation of my sock drawer; who knows.
If you would like to find out, or even see what the Hubspot plugin looks like in action, sign up from the Welcome page.
