Klaviyo: Email Marketing & SMS

My email photos are broken, and the emails look like a joke on the free plan. You get what you pay for. When I tried to upgrade, the least expensive plan I can purchase is $350 a month!!! What a joke. First of all, my niche does not do well with email marketing; I need minimal emails, but I need to them to be professional. Klaviyo emails ruin my credibility. Can't get any customer service because I refuse to pay $350!
