AI Cold Email for B2B Outbound
Founder of Link AI. Writes about voice agents, cold email, and the operational reality of running them in Hebrew and English.
B2B outbound is the use case Mailer was built for. Describe your ICP, hand over a target list (or have Mailer source one), and Mailer ships personal emails plus two follow-ups per lead. The reply-handling layer routes positive replies to a human, reschedules out-of-office, and quietly removes hard-bounced addresses. Sample campaigns hit 70-80% open rates and 7-12% reply rates on tight ICPs in both Hebrew and English.
Why most B2B outbound fails
Most B2B outbound campaigns fail for one of three reasons: bad ICP (loose targeting), bad copy (templates that smell like templates), or bad infrastructure (cold domains, no warmup, no reply handling). Mailer addresses all three, but the highest-leverage one is copy — because tight ICP and warm infrastructure with bad copy still gets 2% replies.
What Mailer does for B2B outbound
Mailer takes a natural-language ICP description, sources matches (or accepts your list), enriches each lead with research, and writes per-lead emails plus two follow-ups. The reply-handling layer routes positives to a human, reschedules out-of-office, and removes hard bounces. Deliverability infrastructure (warmup, mailbox rotation, per-mailbox monitoring) is built in.

How Mailer runs a B2B campaign
Example: a B2B SaaS selling into mid-market manufacturing. ICP: 'COOs at manufacturing companies in Israel with 50-500 employees that have shipped a digital-transformation initiative in the past year.' Mailer pulls ~80 matches, enriches each with their company's recent digital announcements, and writes 80 distinct emails that reference the specific initiative and connect to the product's relevant feature.
ROI math for B2B outbound
A team of 2 outbound reps sending 300 emails each per week (600 total) at template quality books 3-6 meetings per week. Mailer at the same volume — but per-lead writing — typically books 15-30 meetings per week, because the reply rate moves from 1-2% to 6-10%.
Frequently asked questions
How does Mailer compare to Outreach or Salesloft?
Outreach and Salesloft are cadence tools — they send sequences. Mailer is the writer — it does the per-lead research and writes the body. You can use Mailer plus a cadence tool, but most teams find Mailer's built-in cadence enough.
What does deliverability infrastructure include?
Domain warmup (4-6 weeks before any outbound), mailbox rotation, per-mailbox health monitoring, SPF/DKIM/DMARC setup verification, and automatic pause on inbox-placement drops.
Can I see example emails before launching?
Yes. Mailer writes a 5-lead preview before any campaign launches. You approve or reject the tone.
Hebrew outbound?
First-class. The Hebrew model is not a translation layer on top of English — it was trained on real Hebrew B2B outbound.
