Outbound on Smartlead, engineered for the inbox and written for people.

Smartlead is a cold email platform designed for sending outbound at scale. It lets you connect a large number of mailboxes, warm them up automatically, rotate sending across them and run personalised multi-step sequences. A master inbox brings every reply into one place, and features such as subsequences, webhooks and white-label client access make it popular with agencies and sales teams managing many campaigns. Used well, it gives you a reliable way to start conversations with new prospects while keeping deliverability under control.

A Smartlead agency plans, builds and runs your cold email programme on the platform. At Vertical that covers strategy and targeting, buying and configuring domains, mailbox setup and authentication, warm-up, list building and verification, sequence writing, testing, reply management, CRM integration and reporting. You get a senior team that understands both the technical side of deliverability and the craft of writing to busy decision makers, focused on turning Smartlead into a steady source of qualified meetings for your sales team.

Smartlead is built for volume and control. It handles large numbers of mailboxes, includes warm-up as standard, rotates sending automatically and offers a master inbox that keeps replies from every account in one view. Its API, webhooks and client management features make it flexible for teams running several campaigns or brands at once. Those strengths make it a good fit when outbound is a serious, ongoing channel, though they also mean the setup needs care to avoid damaging sender reputation.

We send from secondary domains rather than your main company domain, with SPF, DKIM and DMARC configured on every one. Each mailbox is warmed up before it carries campaigns, volumes increase gradually and daily limits stay conservative. Lists are verified to keep bounces low, and copy is written in natural plain text without heavy links or tracking. We monitor placement, bounces and replies continuously, resting or replacing mailboxes when signals change, so the programme stays healthy as it grows over time.

It depends on how many prospects you want to reach and how safely each mailbox can send. Rather than pushing high volume through a few accounts, we spread sending across enough mailboxes that each one stays within conservative limits. We work backwards from your targets, the size of your addressable market and your sales team’s capacity to follow up, then recommend a setup that is sustainable. Sending more than your team can handle or your market can absorb rarely improves results.

The master inbox collects replies from every connected mailbox into a single view, so nothing gets missed when campaigns run across many accounts. Replies can be categorised by intent, such as interested, not now or unsubscribe, and assigned to the right person. We manage the inbox day to day, responding to interested prospects quickly, logging objections and removing anyone who asks to opt out. That speed of response often makes the difference between a booked meeting and a lost opportunity.

B2B cold email can be lawful in the UK when it is handled responsibly. PECR treats corporate subscribers differently from individuals, and UK GDPR requires a legitimate interest, transparency about who you are and a simple way to opt out. We target business contacts for whom your message is genuinely relevant, document the approach, include clear opt-out handling and honour every unsubscribe. We are not a law firm, so for specific circumstances we always recommend you take your own legal advice.

Yes. Smartlead integrates with CRMs such as HubSpot and Pipedrive, and its webhooks and API make it possible to connect almost any system. We set it up so interested leads and booked meetings are created or updated in your CRM with the right owner and stage, and so current customers and open deals are excluded from outreach. That keeps your sales team working from one accurate record and lets us measure outbound in pipeline and revenue rather than in emails sent.

We start with research into your market and the problems your best customers faced before they bought. Each email makes one clear point, relates it to the reader’s role or situation and asks one easy question. We keep messages short, plain and free of jargon, and personalise around details that matter rather than surface facts. Variants are tested on angle, subject line and timing, and every sequence is reviewed by a senior writer before it reaches a single prospect in your market.

All three are capable platforms with different strengths. Smartlead suits teams and agencies running large mailbox fleets who want flexibility through webhooks and an API. Instantly offers a simple way to scale email with a built-in lead database. Lemlist is strongest for rich personalisation and sequences that combine email with LinkedIn. We work across all three and recommend the one that fits your volume, workflow and budget. If you already use one, we can usually improve results without a switch.

Start with a conversation about your market, your ideal customers and what you have tried so far. We then propose a plan covering infrastructure, targeting, messaging, reply handling and reporting, with a realistic timeline that allows for proper warm-up. If you already run Smartlead, we usually begin with an audit of your domains, mailboxes, campaigns and data. Either way, you will get a straight answer on whether outbound suits your business and what it will take to make it work.
