Interakt has a 30% failure rate and charges merchants without notice.
There's a better option.
Interakt is one of the most-reviewed WhatsApp apps on the Shopify App Store. It's also one of the most-complained-about — for the same two issues: automations that silently fail, and billing that charges cards without merchant approval.
Problem 1: Automations that silently stop working
Interakt's most common recurring complaint is automation failure — order confirmations, shipping notifications, and COD messages that simply don't send. The problem isn't occasional; merchant reports document 30% failure rates on COD confirmation specifically, and it goes undetected because Interakt's dashboard doesn't surface failures clearly.
For COD merchants, this is catastrophic. Every unconfirmed order is a potential fake — an order that ships with a 35% chance of non-delivery. A 30% automation failure rate means a third of the protection you paid for isn't working.
"Order confirmations fail about 30% of the time, shipping confirmations about 10% of the time. I only found out because a customer mentioned they never got a message. The app gives you no indication that messages aren't being delivered."
"Templates keep getting disabled without warning. One day automation is working, the next it just stops and you have no idea until you check manually. Support takes 24-48 hours to respond."
"We had Interakt running for 4 months. I discovered by accident that our COD confirmations had stopped sending 3 weeks earlier — 200+ orders had shipped without verification."
Problem 2: Unauthorized charges
Interakt's billing model adds WhatsApp conversation fees — Meta's per-message rates — on top of the monthly subscription, and charges them through a separate payment method (credit card or Interakt wallet). Several merchants have documented charges appearing without explicit approval or clear notification.
Because Interakt doesn't bill through Shopify, you can't cancel from your Shopify admin. You have to contact their support team — and merchants report difficulty getting refunds even for charges they didn't authorize.
"Charged my card without authorization multiple times. When I tried to cancel, the process was unclear and support was slow to respond. I had to dispute the charges with my bank."
"They deducted money from my account without any prior notification. The support team was not helpful in resolving the billing dispute."
"Billed extra charges without clear explanation of what triggered them. No breakdown, no invoice, just a deduction."
WASP bills exclusively through Shopify. You approve the charge once in your Shopify admin — just like any other app. No separate credit card. No wallet. No meta-level message fees added on top. Cancel anytime by removing the app from Shopify.
How WASP makes sure every message sends
WASP uses a durable task queue. Every confirmation task is written to the database before it's attempted. The system retries failed sends automatically — up to 10 times — with exponential backoff. If it still can't send, you get notified. There is no silent failure mode.
