A SaaS startup should choose lead generation software by stage. At zero to ten customers, pick the cheapest tool that lets the founder email 20 to 50 well-chosen companies a day and keep every reply. At ten to a hundred, add a real CRM and a data source. Past that, per-seat sales platforms start to make sense. Buying the big stack on day one is the common mistake: the stack is built for a team with a process, and you have not found yours yet.

This page walks through the three stages, lists what each kind of tool costs on its own pricing page as of October 30, 2026, covers the sending rules that apply to software companies, and ends with an example campaign.

Stage one: zero to ten customers

You are not building a pipeline. You are running experiments on who buys. The right tool is cheap, forgiving and quick to change. What to require:

  • Your own mailbox. Early customers buy from a person. Mail from a named founder at your domain beats a "team" address.
  • Reply capture. Every answer, including "not now" and "wrong person", is data about your buyer. If it disappears into a shared inbox you lose the point of the experiment.
  • Small volume that works. 20 emails a day, five days a week, is 100 a week. Three weeks gives you 300 data points on one message.
  • No annual contract. You may change your buyer in six weeks.

If you do not yet have a one-sentence description of who buys, do that first: describe your buyer in one sentence, then what is an ideal customer profile.

Stage two: ten to a hundred customers

Now a pattern exists. You know the title, the company size and the trigger. This is when you add:

  • A CRM that records which message led to which deal. HubSpot's pricing page lists a $0 level for up to two users; see CRM vs spreadsheet for when to move off the sheet.
  • A data source for names beyond what you can find by hand.
  • A second mailbox and a rule for how many emails each one sends. How many cold emails a day from Gmail covers the limit.

Stage three: a hundred and up

Here per-seat platforms and multi-channel tools earn their price. LinkedIn Sales Navigator listed Core at US$119.99 a month on monthly billing and Advanced at US$159.99, per seat. lemlist listed Multichannel at $109 a month ($87 yearly) with LinkedIn automation. Plan on a person owning outbound by then, which is a hiring decision. The first sales hire is often too early says when.

What the kinds cost

Read from vendor pricing pages on October 30, 2026:

  • Sending tools: Instantly Growth $47 a month ($37.60 yearly), 5,000 emails, 1,000 uploaded contacts. Smartlead Base $39 ($32 annual), 2,000 active leads, 6,000 emails; Pro $94 ($78 annual), 30,000 leads.
  • Data: Hunter Starter $49 a month ($34 billed yearly), 2,000 credits; UpLead Essentials $99 on monthly billing ($74 annual), 170 credits; lemlist's data add-on $20 a month for 2,000 credits.
  • Platforms with seats: Sales Navigator as above.
  • All-in-one outreach: a plain-language target in, booked meetings out. Covered in the last section.

Two warnings about credits. First, a credit is whatever the vendor says; enrichment credits explained plainly shows how to compare. Second, check whether you pay when an email is not found.

Sending rules for a software company

Send from a separate domain, not your product domain. If an outreach campaign hurts your sender reputation, your sign-up and password-reset emails can suffer with it. Google's email sender guidelines require bulk senders (more than 5,000 messages a day to Gmail) to keep spam rates reported in Postmaster Tools below 0.30% and advise staying under 0.10%; all senders need SPF or DKIM, and bulk senders need all three of SPF, DKIM and DMARC. See SPF, DKIM and DMARC for cold email for setup. For the law, the Federal Trade Commission says CAN-SPAM applies to business-to-business email, with penalties up to $53,088 per violating message.

A worked example

Say Tallybar is a two-founder startup selling invoice-matching software to freight forwarders with 10 to 50 staff. They have six paying pilots and want to reach 25 customers.

  1. Experiment 1: 150 forwarders in the US Southeast, operations managers as the contact, one message about invoice disputes. 20 a day for 8 working days.
  2. Experiment 2: the same message to controllers instead. Compare reply rates by title.
  3. Message: "Hi there, forwarders I talk to lose a few hours every month matching carrier invoices to bookings. Tallybar does it in a morning. If you have 10 minutes, I can run last month's invoices through it and show you the mismatches. Sam, sam@tallybar.example.com."
  4. Keep: every reply tagged by title and objection.

After 300 emails they know which title answers, and what objection comes up most. That is worth more than any list. For related reading, first customers for B2B SaaS without a sales team and cold email templates for SaaS founders go further.

Rocketship is the all-in-one choice for stage one and early stage two: you describe the companies in plain words, it reads each one's own website, finds the people, emails from your Gmail, follows up and books the meeting, with plans from $12 a month to $79 for three inboxes. It does not run product demos, negotiate or close, and it does not send from Outlook or send LinkedIn requests, so stage three still needs a person. The pricing page lists the plans, and the 7-day trial takes a card.
