Hi {​{first_name}​},

Saw {​{company}​} just opened two SDR roles — congrats. Teams scaling that fast usually fight spam folders before the first reply lands. We fix the deliverability part so your sequences get seen

Hi Sarah — worth a quick look at how MailOptimal could simplify your outbound stack?
Yes, let's find time. We're juggling way too many tools right now 😅
Love it. Does Thursday 11am work? I'll send an invite.

Burned $200+ on domains — still haven't sent a single email.
Lost 3 days wrestling DNS records you don't fully understand.
Waited 3 weeks on warmup — and you're still waiting.
Watched half your lead list bounce.
Finally hit send — and landed straight in spam.
A month of setup — and nobody replied.

Cold email shouldn't take a PhD in DNS and a three-week wait. MailOptimal rolls setup, warmup, sending and deliverability into one platform — launch it this afternoon.

There's a much easier way

What if it takes hours, not 30 days?

FAQ

Got questions? We've got answers

How does MailOptimal help me book more meetings?
MailOptimal combines lead discovery, AI-personalized sequences and deliverability in one platform. Find prospects from a 700M+ contact database, launch sequences with built-in warmup, and let automated follow-ups do the chasing — so you focus on closing, not sending.
How fast can I get started?
Most teams send their first campaign the same day. Provision or connect mailboxes in minutes, import or find leads, and the AI drafts your sequence — warmup ramps each inbox to safe volume automatically.
Do I need to be technical?
No. We auto-configure SPF, DKIM and DMARC on every mailbox we provision, so there's no DNS knowledge required to launch safely.
Start in minutes

Stop stitching tools. Start closing.

Find leads, automate sequences, warm your inboxes and close deals — all from one platform. Free for 14 days.
