Klaviyo: Email Marketing & SMS

Pricing is really predatory, it increases waaay above what they initially show and they automatically charge you more. When installed, it created a bunch of fake accounts which were just Google Bot "subscribers" with fake emails and now charges me at a much higher price tier just because it considers those somehow to be real people and counts them toward my total. Pretty ridiculous. They don't prorate nor will they allow any free trial or test of their email system. Templates for emails weren't very good and were difficult to use.
