Six numbers that say everything.
Rolling 90-day metrics across every active customer workspace. Updated nightly, never cherry-picked.
Cold email is broken. Most of it never lands.
Every week you ship outbound without proper infrastructure, you burn budget, reputation, and reps.
- ✕78% of cold emails never reach the primary inbox.
- ✕Reps spend 6+ hrs/week on manual list cleanup and follow-ups.
- ✕Most teams lose $40k+/month to bounces, spam, and silence.
- ✕One bad sender domain can blacklist your whole company.

A week with Sendlyst, mapped.
The agents do the busywork. Your team spends 4 hours a week on the parts that move pipeline — reviewing drafts, replying to interested leads, and tweaking copy that's underperforming.
Stop duct-taping six tools together.
Most teams stitch a CRM, a warmup service, a sender tool, and a personal Loom for replies. We replace all of it.
Six reasons teams switch.
Built by operators who ran outbound at scale. Every feature exists to remove a real bottleneck.
>85% primary inbox placement, audited monthly.
No per-seat or per-inbox tax. Scale to 500 senders.
Per-lead research → unique opener for every email.
All replies in one place with AI triage and forwarding.
Real onboarding, not a sales call gate.
Flat rate. No 'contact sales' for under 100k contacts.
The metrics that matter, all moving up.
Based on the trailing 90 days across 2,400+ active customer accounts.
Built for teams that need pipeline.
Whether you're hunting your first 10 customers or running 500 inboxes for clients, the workflow is the same.

The six objections we hear most. Answered.
Before you book a demo, this is what the room is usually thinking.
We detect risk on connect and won't let you launch until reputation is safe. Auto-pause kicks in at 3% bounce.
No. The agent researches each lead (LinkedIn, site, news) and writes a unique opener tied to real context.
Yes. 1-click import from Smartlead, Instantly, Lemlist, Saleshandy. Sequences re-mapped 1:1.
Median onboarding is 14 minutes per rep. No training videos required. It looks like Gmail.
Never. Native sync with HubSpot, Salesforce, Pipedrive. Replies and opens flow back automatically.
Yes — when it lands. Our customers average 8.4% reply rates. Pipeline is up, not down.
Plays nicely with your stack.
Native integrations for the tools your team already lives in. Plus a full REST API and webhooks.
Enterprise-grade, even on the starter plan.
We treat your data and your sender reputation like our own.
Twelve questions, answered.
How is deliverability so high?+
Continuous warmup, mailbox rotation, real-time spam linting, DNS monitoring, and automatic pause-on-bounce. Median primary inbox placement is 91% across active customers.
Do I need to connect my own email account?+
Yes — but it takes 2 minutes. Sendlyst supports Gmail, Outlook, and any SMTP/IMAP provider. We never store your password; we use OAuth where possible.
Is cold email legal?+
B2B cold outreach is legal in most jurisdictions when you follow CAN-SPAM, GDPR, and CASL. Sendlyst includes auto-unsubscribe, identity disclosure, and audit logs to keep you compliant.
Can I use my existing CRM?+
Yes. Native integrations for HubSpot, Salesforce, Pipedrive, Apollo, and Clay. Anything else works via webhooks or the REST API.
What if my domain has bad reputation?+
We detect it on connect, recommend remediation (often a fresh subdomain + 14-day warmup), and won't let you launch until it's safe.
How is pricing structured?+
Flat monthly fee based on active contacts. Unlimited mailboxes, unlimited sequences, unlimited users included. No per-seat or per-inbox tax.
Do you offer agency pricing?+
Yes. The Agency plan covers unlimited client workspaces with white-label options. Contact us for volume discounts above 100k contacts.
What models power the AI?+
We use a mix of frontier models (GPT, Gemini, Claude) routed by task. You can override and choose your own model per campaign.
Can I import existing sequences?+
Yes. Drop a CSV of subject/body/delay rows or paste from your old tool. The AI editor will clean it up and suggest improvements.
How fast can I start?+
Median first-launch time is 14 minutes from signup. Warmup runs in parallel so you can build the campaign while reputation is being built.
What happens to replies?+
Real replies forward to your normal inbox + appear in the unified Sendlyst inbox. AI tags them as interested / not now / unsubscribe / out-of-office so you focus on the warm ones.
Do you offer a free trial?+
Yes — 14 days, no credit card. You can connect a mailbox, import 500 leads, and launch a real campaign on day one.
