> ## Short answer
> 
> **Smartlead** if you want the best price-to-deliverability ratio, **Instantly** if you want the smoothest onramp. Those two are the real contenders for 90% of startups; everything else is a situational pick.

> **1. Smartlead** - my default recommendation. Unlimited mailboxes and warmup on *every* tier (including the ~$39/mo base), one of the biggest warmup networks, solid API, and a master inbox that doesn't fall over when you're running many sending domains. This is the one to pick if you expect to scale sending volume and don't want per-seat or per-inbox pricing punishing you for it. Known gripes from reviews: mailboxes occasionally disconnecting mid-campaign, slow support, and add-on cost creep. 4.6/5 on G2 across ~300 reviews.

> **2. Instantly** - pick this if you're a founder doing outreach yourself and want to be sending this afternoon. Best UI in the category, strong warmup, and it bundles a lead database + light CRM so you don't need a separate data vendor on day one. Entry sending plan is ~$37-47/mo; the bundles that include
