> # Best cold email software for startups
> 
> Here's what I'd actually recommend, roughly in the order I'd suggest you try them:
> 
> **1. Instantly** (~$37-47/mo) - My default pick for a founder doing their own outreach. Unlimited mailboxes and built-in warmup on every plan, sender rotation across inboxes, a 450M+ lead database included, and the cleanest UI of the bunch. You can be sending the same day without stitching tools together. Start here unless you have a specific reason not to.
> 
> **2. Smartlead** (~$39/mo) - Pick this over Instantly if you're technical or running outreach for clients. API-first architecture, white-label capability, excellent deliverability controls. Cheaper base price, but you bring your own lead data and agencies pay ~$29 per client seat.
> 
> **3. Lemlist** ($69/mo email, ~$109/user/mo multichannel) - Worth the premium only if LinkedIn steps matter. It's the one of the three that natively automates LinkedIn alongside email, and its personalization tooling is the strongest. Best fit for high-touch, low-volume outreach post-PMF rather than spray-and-pray.
> 
> **4. Apollo.io** ($49/user/mo) - The "one tool, zero setup" option: data, sequencer, dialer, and CRM sync in one
