Verbiflow is sequencing infrastructure for growth teams. Run multi-step sequences across email, LinkedIn, and cold calls from one platform, handle sending and deliverability, and land replies in one shared inbox so your whole team stays aligned.

What can I do for free?

Sign up free with no credit card. You get three starter sequences personalized to your company, and you can build sequences, import a CSV, and connect a mailbox to test. Launching real sends requires a paid plan, starting at $50/month.

Can I run it from my AI agent?

Yes. Run npx -y growth-mcp install to add Verbiflow to Claude, Cursor, or Codex. It turns your coding agent into a GTM operator that can research accounts, build lists, draft sequences, and run plays from chat.

Do you support cold calling?

Cold calls are in early access. Today, sequences run across email and LinkedIn. If calling is part of your motion, book a demo and we'll get you access.

Do I need to bring my own mailboxes and domains?

You can do either. Connect your existing Gmail or Microsoft accounts, or buy sending domains and provision outbound-ready mailboxes directly in Verbiflow. We handle warming and run inbox-placement checks so your deliverability stays strong.

Email and LinkedIn replies land in one shared inbox where your team can respond directly. You're alerted by email and Slack the moment a prospect replies, and all send and reply activity syncs to your CRM so the whole team stays aligned.

A play is a complete outbound motion: we retrieve a targeted list of accounts and contacts, qualify and segment them, then sequence them across email and LinkedIn. The examples above are real plays we ran. Build your own with the agent, or have us build a custom one for your accounts.

How does pricing work?

Verbiflow is free to explore, with paid plans from $50/month. Plans are priced on monthly contact credits plus sending seats (mailboxes and LinkedIn accounts). Credits cover sourcing and enrichment. See the pricing page for full details.

Outbound infra·May 28, 2026·4 min read

Outbound is an infrastructure problem, not a tool problem

By The Verbiflow team

Every growth team has the same outbound stack now: Apollo for lists, Instantly for email, HeyReach for LinkedIn, Orum or Nooks for calls, a warmup tool, and a mess of Zaps holding it together. None of these tools are bad on their own. The trouble is that running outbound across all of them is now an infrastructure job, and most teams are still buying it like software.

A sequencer queues messages. Infrastructure decides whether you have capacity, whether the domains stay healthy, who owns the prospect, what channel fires next, and where the reply lands.

What infrastructure actually decides

Sending capacity. Not how many emails your sequencer can queue. How many emails your provisioned mailboxes can safely send today without risking the domains behind them.
Deliverability. Warmup, SPF/DKIM/DMARC, inbox-placement checks, and rotating senders when one starts to degrade.
Channel routing. If email bounces, fall to LinkedIn. If LinkedIn accepts but the person doesn’t reply, queue a call step. Every step depends on what happened in the previous one.
Reply handling. Every channel produces replies. They all need to land in one place your team actually checks, with the sequence context attached.
Identity. One prospect, one owner, one history across every sequence and every channel.

The duct-tape stack

Apollo for lists. Instantly for email. HeyReach for LinkedIn. Orum or Nooks for calls. A separate warmup tool. A Zap layer trying to glue the inboxes. Five logins, five billing cycles, and replies that surface 36 hours late because nobody noticed the LinkedIn DM.

If this is what your stack looks like today, you may be entitled to verbiflow :)

Where it actually breaks

Outbound doesn’t usually break because Apollo, Instantly, HeyReach, or your CRM is bad. It breaks when one campaign has to move across all of them and none of the systems share the same state.

You pull 5,000 leads from Apollo or Clay. Your provisioned mailboxes can only support a safe daily volume. Some of those people are already customers, some are already in another sequence, some emails bounce and need to move to LinkedIn, and replies come back across email, LinkedIn, and calls.

The hard part is not pressing send. The hard part is keeping capacity, suppression, routing, ownership, replies, and reporting in sync while the play is running. That work is the infrastructure layer.

What infrastructure-first looks like in Verbiflow

Verbiflow is the run layer after the list is sourced. Bring leads from Apollo, Clay, Crunchbase, a scraper, or a CSV. Verbiflow handles the parts that decide whether the outbound actually runs cleanly:

Domains and mailboxes provisioned in-platform. Buy a domain, auto-wire SPF/DKIM/DMARC, warm the mailbox, rotate senders. No DNS tickets, no separate warmup subscription.
Safe sending capacity. The sequence respects what your provisioned mailboxes can safely support instead of treating volume as a spreadsheet number.
Dedup and suppression. Customers, active opportunities, recently touched accounts, and prospects already in another sequence get filtered before outreach starts.
Email and LinkedIn in one play. A bounce, no-reply, accept, or reply can move the person to the next right step without someone exporting another CSV.
One inbox and clean CRM sync. Sends, replies, bounces, unsubscribes, and meetings sync back with attribution, so reporting stays usable.
SDK for custom plays. Use Claude Code or Cursor to source from Crunchbase, Apollo, or your own scraper, then push the audience into Verbiflow without rebuilding the same workflow by hand.

The data tools can keep doing what they do best. Verbiflow takes the sourced list and makes it usable for outbound, with safe volume, correct suppression, the next channel already wired up, one reply view, and CRM reporting that holds up after the play goes live.
