I can only say good things about Waitlister...and I am a picky/difficult client. Their landing page is very user friendly, and Devin (the owner) directly answers your emails very rapidly - there is no customer service in a foreign country which can be burdensome. I have checked competitors, and Waitlister's pricing is more than reasonable (I don't like to criticize the competition, so please do your own homework). I am building up a waitlist with a very small budget, and Waitlister appeared to be the best choice for my goals and my budget. I wish you all the best luck in your endeavors.
