When to replace Instantly
Buyers must compare three pricing tracks: Bundle, Outreach-only, and Credits-only. The tracks overlap but do not include the same allowances. The retained pricing material assigns SISR server and IP rotation to Agency or the higher-volume outreach tiers, while Enterprise pricing is custom. Teams that need only low-volume sending or only lead data should compare the included database, email, and AI credits against actual use before choosing a bundle.
