Which plan to pickStart on Free to see if you will actually post regularly. Move to Essentials once you need more than 10 posts queued per channel; Team is only worth it when someone else needs to approve posts.Start on Free and build your welcome and abandoned cart flows before you pay anything. Move to Email when you cross 250 contacts, and only add SMS once email is working, because text messages cost extra per send.Your plan is set by your monthly Meta ad spend, not by features: every tier gets the full product. Most small brands will land on Starter. Agencies should book a call for a custom price.

Pros and cons

AttributeBufferKlaviyoParker
Pros
  • Very easy to learn, with a clean interface
  • Real free plan, and low per-channel prices
  • Covers almost every network, including Threads, Bluesky and Google Business Profile
  • AI Assistant is included on every plan
  • Public API and official MCP server
  • Deepest store integration of any email tool, so targeting runs on real purchase data
  • Flows and segments are quick to set up from templates and plain English
  • Email and SMS live in one place with one set of customer data
  • Predictive analytics tell you who to spend effort on
  • Huge ecosystem of Shopify apps and agencies that already know it
  • Covers the research and briefing work most ad tools skip
  • Uses your own reviews, comments and ad data, so ideas are specific to your brand
  • Unlimited usage and team members on every plan
  • Built by a working ad agency, so the frameworks come from real campaigns
  • MCP server for working with it in Claude
Cons
  • Analytics are basic next to Hootsuite or Sprout Social
  • Per-channel pricing climbs quickly once you manage many accounts
  • Some users report posts occasionally failing to publish or duplicating
  • No social listening, and the inbox is lighter than a full social suite
  • Gets expensive fast as your list grows, and every profile counts toward the bill
  • SMS is a separate cost on top of the plan
  • Email support stops after 60 days on the free plan
  • Overkill for service businesses and plain newsletters
  • $299 a month minimum with no free plan, so it is out of reach for small or new advertisers
  • Very new, with no independent reviews yet; nearly all the praise is from the company or its own customer quotes
  • Writes ideas and briefs only, it does not make the ads
  • Built around Meta ads; Google and other channels get little attention
