Everything else is a detail.\n\n## In order\n\n**1. Instantly.ai** - the default pick for a startup sending its first cold emails. Unlimited mailboxes on most plans, built-in warmup, and the cleanest setup flow, so you can go from domains purchased to sequence running in an afternoon. Outreach-only plans start around $37-47/mo; their 2026 bundles (Starter $94, Scale $194) add a lead database and light CRM, which you probably don't need on day one. ([instantly.ai](https://instantly.ai/blog/instantly-vs-smartlead-lemlist-2026/))\n\n**2. Smartlead** - the better choice if you're comfortable in an API and want infrastructure rather than a product. Unlimited mailboxes and warmup on *every* tier including the $39 base plan, strong per-inbox deliverability controls, and white-labeling if you ever run outreach for other companies. Email plan is priced per workspace with unlimited users (~$69), which gets cheap fast once more than one person is sending.
