Common questions about SleekFlow vs Instant Reply
Is InstantReply better for WhatsApp than SleekFlow?
If your DMs include voice notes or product photos, yes. SleekFlow's AI is text-only and the pricing is MAC-based, which means a successful campaign raises your bill. Instant Reply transcribes voice notes, reads product photos, runs a Hormozi-trained closer, and prices by plan capacity instead of MACs. Growth at $129/mo ($107.50 annual) vs SleekFlow Pro AI at ~$103/mo — close on sticker, but Instant Reply ships voice + vision + closer that SleekFlow doesn't.
Does InstantReply have MAC-based pricing?
No. InstantReply prices by plan capacity, not Monthly Active Contacts. You don't get a surprise bill when a campaign goes well.
Can I use my Shopify or HubSpot integration?
Yes. InstantReply syncs to HubSpot and Pipedrive natively, and integrates with Shopify via Zapier or direct webhooks.
Does InstantReply have a free plan like SleekFlow?
No free plan. You get a 10-day Pro trial with no credit card. That's enough to test the workflow end-to-end before paying.
