What the entry plans include

Instantly's Outreach Growth plan costs $47/month and includes unlimited email accounts and warmup, with room for 1,000 uploaded contacts and 5,000 emails a month. Smartlead's Base plan costs $39/month for 2,000 contacts, 6,000 sends and 2,000 verified emails. On paper, Smartlead's entry plan gives you a bit more room for less.

How costs grow

Instantly sells leads as separate credits plans (Growth credits also start at $47/month) and also offers bundles that combine outreach, leads and AI agents. If you want both sending and lead data, add the two together. Smartlead puts verified prospect emails inside each plan and jumps to unlimited contacts at the $174 Unlimited Smart tier, which is where high-volume senders usually land.

Automation and agencies

Smartlead is built API-first, and its plan comparison lists API & webhooks, client workspaces and private infrastructure among its features. Instantly leans into AI, with a Sales Agent, AI Reply Agent and Unibox replies in its bundles, plus private server and IP rotation on Light Speed.

Our take

Both are in our Best AI Outbound & Lead Gen Tools list. Our verdict calls Instantly "the go-to cold email sender for founders and agencies", and Smartlead "Instantly's closest rival", a good fit for high-volume senders who automate through the API. Whichever you pick, warm up new domains before sending.

Bottom line

Instantly is the easier all-round choice, but the full stack costs more than the $47 headline because leads and CRM are billed separately. Smartlead starts lower at $39 and suits API-driven or agency workflows, though Base caps you at 2,000 contacts and 6,000 sends a month.
