If you are still looking for your first users, read our guide on how to get your first 100 SaaS users for the full acquisition playbook. But it only works with the right tool, proper setup, and respect for deliverability.

Deliverability tips#
The best cold email tool in the world is useless if your emails land in spam. Follow these rules.
Domain setup: Use a separate domain for cold outreach. Never send cold email from your primary domain. Set up SPF, DKIM, and DMARC authentication.
Warmup: Warm up new email accounts for 2-3 weeks before sending at volume. Most tools above include built-in warmup features.
Volume: Start with 10-20 emails per day per account. Gradually increase over weeks. Sudden volume spikes trigger spam filters.
Content: Avoid spam trigger words, excessive links, and HTML-heavy emails. Plain text with one link performs best. Keep emails under 5 sentences.
List hygiene: Verify every email address before sending. Bounced emails destroy your sender reputation. Hunter.io and other verification tools help.
FAQs#
Which cold email tool is best for a solo SaaS founder?#
Instantly or Apollo.io. Instantly offers the best deliverability with unlimited accounts at $30/month. Apollo has a free tier with a massive contact database that saves time on prospecting.
Is cold email legal?#
Yes, if you follow the rules. In the US, CAN-SPAM requires a clear opt-out mechanism and honest subject lines. In the EU, GDPR requires legitimate interest and easy unsubscribe. B2B cold email is generally permitted in both regions when done correctly.
How many cold emails should I send per day?#
Start with 10-20 per day per email account. Increase gradually over 2-3 weeks. Sending 100+ emails from a new account on day one will get you flagged as spam.
What reply rate should I expect?#
A good cold email campaign gets 5-15% reply rates. If you are below 3%, your targeting or messaging needs work. If above 20%, you have found a strong product-market fit signal.
Should I use cold email before or after launching?#
Both. Before launch, use it to find beta users and validate messaging. After launch, use it for sales outreach, partnership building, and backlink outreach to grow your domain authority.
Building backlinks through outreach?
RankInPublic gives you dofollow backlinks through weekly tournaments. No outreach required.
