Marketing teams often struggle with time-intensive campaign setup, inconsistent customer experiences across channels, and limited ability to provide 24/7 customer support while maintaining brand voice and selling opportunities.

“The problem with using ChatGPT to build campaigns isn't the copy. It's that ChatGPT doesn't know your segments, your catalog, or what's actually converted for your customers, so the setup still lands on you. Composer does. It's built on your data, grounded in 14+ years of perform”
“Klaviyo is a scam. They had a rep, a Julie D. from the sales department contact us about setting up emails for our company. We had over $35k emails which cost over $800+ for just one month. I was promised an onboarding, Julie told me someone was going to call me and help me setup”

“You’re missing out on a lot of functionality using Shopify email. If your store grows big, email revenue will most likely be your biggest channel. When you say Shopify email has 90% functionality… I think it’s probably closer to 30%. I would take this discussion to r/klaviyo You ”

“Don't get lured in by the Shopify integration alone. Klaviyo has become an endless money pit where you pay a premium for 'bloatware'—features that sound good on paper but offer no real utility. Their pricing keeps climbing, yet the customer service remains abysmal. For the price ”
“Solid features but support and pricing has lost the plot. | They used to be great at supporting their accounts, but now default everything to chat support and a shared email box. For the price you pay, this is not an acceptable level of support. | Pros: Easy to create segments | ”

“When a flow or automation stops working due to Klaviyo fault, customer support is truly useless. No ETA to fix it, no refund or reduction of monthly fees to help cover loss of revenue. ”
