Comparing Clay’s Sequencer vs Instantly for Outbound Email: Deliverability, Pre-Warmed Domains, and Pricing Tiers Ins...

We're setting up our outbound stack with Clay handling enrichment, validation, and AI copy, and trying to decide between Clay's native sequencer and Instantly for the sending side. The main thing I'm trying to understand: does Clay's native sequencer offer pre-warmed sending domains and mailboxes the way Instantly does? That feels like the biggest practical differentiator — Instantly's pre-warmed accounts mean you can start sending immediately without going through a warmup period yourself. Has anyone used Clay's sequencer in production and compared deliverability to Instantly? Would love to hear honest takes. Also — for those running this kind of setup at a seed stage with relatively modest volume (~500 contacts/month, 4-5 step sequence): which Instantly tier are you on, and is Growth ($47/month) sufficient or did you find you needed Hypergrowth?
