Instantly.ai vs Smartlead
The two most-debated cold email platforms of 2026. Instantly: Growth outreach plan $47/month (5,000 emails, 1,000 contacts), Hypergrowth outreach plan $358/month; bundles are priced separately, with Starter at $94/month (5,000 emails, 1,000 contacts, 1,500 credits, and the 450M+ B2B leads database included), and credits sold separately from $47/month. Amounts as shown on the pricing page, which does not name a currency; unlimited email accounts and warmup are included on the Growth outreach plan. Smartlead: Base $39/month (6,000 emails, 2,000 contacts), Pro $94/month, Unlimited Smart $174/month, Prime $379/month; unlimited mailboxes and warmup on every plan, white-label client workspaces, and a documented REST API. The practical split from operator reviews: Instantly suits in-house teams that want the lead database built in; Smartlead suits agencies that need per-client workspaces, white-labeling, and API control. No hands-on campaign test was run; no winner is claimed.
