FAQ
Frequently Asked Questions
Learn how Firstsales protects your domain, lands emails in inboxes, and turns cold outreach into revenue—everything in one place.
Cold email is personalized, relevant business communication sent to specific prospects who could benefit from your offering. It's targeted, research-based, and provides value. Spam is unsolicited bulk sent to thousands with no personalization or relevance. The key difference: cold email respects the recipient's time and needs; spam doesn't.
Industry average is 1-3%. Top performers achieve 8%+ through better targeting, personalized messaging, and strong offer-market fit. Reply rates vary by industry—B2B SaaS typically sees 2-5%, while marketing agencies can hit 5-10%. Focus on quality over quantity: 50 highly targeted emails beat 500 generic ones.
21 days for new domains to establish sender reputation. During warm-up, send volume gradually increases from a few emails to your target rate. Skipping warm-up guarantees 90%+ spam placement. Established domains can skip or shorten warm-up, but new domains must go through the full process for reliable deliverability.
SDRs (Sales Development Representatives) focus on the top of funnel: qualifying leads, booking meetings, and generating opportunities. AEs (Account Executives) handle the bottom of funnel: running demos, negotiating deals, and closing revenue. SDRs specialize in outbound prospecting; AEs specialize in closing.
Common causes: new domain without reputation, poor email authentication (SPF/DKIM/DMARC), buying lists, high bounce rates, spam trigger words in subject lines, low engagement rates, and sudden volume spikes. Fix: authenticate your domain, warm up properly, scrub your list, and send targeted, relevant content.
New domains: start with 5-10 emails per day during warm-up, gradually increasing to 20-50. Aged domains (2+ years old) can start higher at 30-50 and scale to 50-100+. Never exceed 100 emails per day per inbox—quality and deliverability matter more than volume. Multiple inboxes can multiply your reach.
Deliverability is the percentage of emails that reach the primary inbox (not spam, not blocked). Industry average: 60-70%. Top performers: 85%+. Poor deliverability kills campaigns—even great copy fails if nobody sees it. It depends on domain reputation, email authentication, list quality, and engagement rates.
Track four metrics: (1) Deliverability rate—emails reaching primary inbox, (2) Open rate—subject line effectiveness, (3) Reply rate—message resonance, (4) Meeting booked—ultimate goal. Reply rate is the leading indicator. If you're getting replies, the other metrics will follow.
