“It's booking five to ten demos a week on its own — I'd put a lot more in if that keeps up… and with barely any instructions the leads are accurate. Other platforms scrape the worst fits ever.”

We run the entire pipeline

From “here's my website” to “demo booked” without a single manual step in between.

  1. Step 1 of 6

    Learns what you sell

    Paste a URL. The agent reads your site, studies your competitors and writes your positioning back to you in plain English.

    larksilk.com

    Wholesale silk flowers and greenery for hotels, restaurants & florists, in business for 45+ years

  2. Step 2 of 6

    Figures out who buys it

    Every plausible segment is scored by fit, so budget goes to the buyers most likely to say yes — not the ones easiest to scrape.

    Writes each a personal email

    One email per person, grounded in what they actually do. No templates, no {{first_name}}, no spray and pray.

    SubjectLarksilk × Tupelo Honey Flower

    Hi Dana,

    Saw Tupelo Honey designs full-scale event installs. At that pace, fresh florals get expensive fast and wilt under venue lights. Larksilk ships premium silk by the box from NJ, so one buy carries across events.

    Want a sample box to compare against your last fresh order?

  5. Step 5 of 6

    Handles replies and books meetings

    Answers questions, works through objections and drops your booking link at exactly the right moment.

    How do these hold up under venue lighting?
    Interesting, can you do Tuesday 2pm?

Common questions

What do I need to get started?

Just your website. Paste the URL and the agent works out what you sell, who buys it, and finds the exact people to contact. Building the lead list is free, and adding a card unlocks $30 in starter credits without charging you anything — so your first sends cost nothing.

How much does it cost?

About $0.03 per email actually sent, and that's the entire model: no subscription, no per-seat fee, no charge for finding leads. You start with $30 in free credits, which covers your first 1,000 emails. After that you set a daily budget that caps spend, and spending stops the moment you pause a campaign.

Whose mailboxes send the emails? Is my domain at risk?

Outreach goes out from our pool of pre-warmed inboxes, never from your own mailbox or domain, so your reputation is never on the line. Each prospect is paired with one inbox that carries the whole conversation, and replies land back inside LeadSpring.

How do you keep emails out of spam?

Every mailbox in the pool is warmed up and authenticated with SPF, DKIM and DMARC, with daily sending caps and gradual volume ramps. Bounce and complaint rates are watched across the whole pool, and any inbox that starts to degrade is pulled out automatically, so one campaign can never drag down the rest.

How much control do I have over what goes out?

Every new campaign shows you its lead list before outreach starts, and you can preview the email against real leads before launch. You steer targeting and tone by chatting with the agent in plain language, and one click pauses everything at any time.

What happens when a prospect replies?

Replies land in your LeadSpring inbox, where the agent answers questions, handles objections and moves interested prospects toward a call. Add your booking link and it routes meetings straight to your calendar. Calendly, Cal.com, HubSpot Meetings and most major schedulers are supported.

Can I bring my own leads?

Yes. Upload a CSV of up to 30,000 contacts and LeadSpring validates every address with the same engine it uses for the leads it finds itself, then writes and sends to them on the normal schedule. Or let the agent build the list for you across 105M+ companies.

Is cold email even allowed?

LeadSpring sends B2B outreach to business addresses with an honest sender identity, and opt-outs are honored immediately. You control the geography of every campaign, so markets with stricter rules can be excluded entirely.

You've heard it all before.
This one costs nothing to test.

Paste your website, get your first warm leads within 24 hours, pay nothing until you decide it works.
