Want a quick win? Include these at the bottom of every email newsletter:
“Leave a G2 review & get a $50 gift card.
Email a screenshot to marketing@xyz.com & we’ll send the gift card.”
“Refer a customer and get $X [after they take a meeting with us / after they become a customer].
Refer them by [doing xyz].”
I’ve done this in the past, & we got new reviews & referrals for basically no additional work.
