Yes, marketing should run outbound sequences, as long as sales keeps the phone. AI and automation have turned sequencing into a campaign skill, and campaign skills sit in marketing. In the go-to-market teams we talk to every week, the shift is already happening: marketing sets the signals, triggers and campaigns, and sales focuses on calling, meeting and closing.

What changed: sequences became campaigns

Yesterday, marketing was limited to paid ads and generic email campaigns. Outbound was the reps' territory: their lists, their sequences, their copy.

Today marketing teams are orchestrating sales sequences directly. The tools tell the story. Platforms like HeyReach automate LinkedIn messages from multiple profiles. Platforms like Instantly automate emails from multiple inboxes. These are not tools a rep configures between two calls. They are campaign tools, with audiences, variants, sending windows and deliverability settings.

Sales engagement tools used to be configured by sales reps. Now they are configured by marketers and growth managers.

AI accelerates the move. Writing twelve variants of a sequence, enriching a list, sorting replies by intent: these used to be a rep's evenings. Now they are a workflow a growth manager builds once and runs every week.

In the French teams we meet, the split is often already real but informal. A growth manager runs the tools, reps get leads in Slack, and nobody has written down the handoff rule. Writing it is the whole job.

The new split: marketing builds the plays, sales plays the game

The division of work we see in the teams that make this work is simple.

• Marketing owns the plays. Signals, triggers, lists, sequences, copy, and the rules for when a contact moves from a campaign to a rep.
• Sales owns the conversation. The call when a signal fires, the meeting, the discovery, the close.

It is about bridging marketing and sales so reps can do what they do best: building connections, not contact lists.

Why this is good for reps

When we asked our users, full-time AEs who prospect for themselves, where their day goes, 37% went to sourcing leads and building lists, against 13% actually prospecting by phone and email. The list is the biggest block of the day, and it is the block marketing is best equipped to own.

Move the list and the sequence to marketing, and the rep gets hours back for the one thing automation does not do: the conversation. Our north-star funnel is 20 conversations per day per rep. That target is only realistic when someone else builds the plays.

There is a second benefit. Marketing measures campaigns for a living. A sequence run by marketing gets variants, a control group and a weekly readout. A sequence run by a rep gets whatever the rep had time for on Friday.

How to set up the marketing-sales split

1. Define each play on one page. Trigger (a job change, a website visit, a hiring signal), persona, channel, message, and the handoff rule to sales.
2. Give marketing the list and the signal stack. CRM signals, website visitors, social intent, enrichment. Marketing maintains the data, not the rep.
3. Give sales a 24-hour SLA on handoffs. A reply, a meeting request or a hot signal gets a call within a day. In our experience, this SLA is the whole system. Without it the play dies in the inbox.
4. Share one metric. Not sends, not opens. Conversations and meetings per play. Marketing and sales look at the same number.
5. Review plays weekly. Kill the plays with no meetings after 200 contacts. Double down on the ones above a 7% meeting rate, which is what trigger-based calls reach in our analysis of 1,000,000 B2B cold calls.

What a good play looks like

Trigger: a new VP Sales joins a company of 50 to 200 employees in France. Persona: the new VP Sales, in their first 90 days. Channel: a LinkedIn connection and one email from marketing within 48 hours of the signal. Handoff: any reply, or a visit to the website within 14 days, goes to the rep's calling session the same day with the "why now" attached. Metric: meetings per 100 triggers, reviewed every Monday.

One page. Anyone in the company can read it and know who does what.

Common mistakes when marketing takes over outbound

• Optimizing for volume. Marketing inherits the "more inboxes, more sends" habit. Sequences are a way to find conversations, not a replacement for them.
• Sales ignoring the handoff. If reps treat sequence replies as marketing's leads, the split fails. Replies are calls to make.
• Automating the call. The phone is the last human channel. Automating it is how you turn a warm signal into spam.
• Going back to MQLs. A contact who opened two emails is not a lead. A contact with a trigger who replied is.
• No shared tooling. If marketing's signals do not land in the rep's dialer, the handoff is a Slack message that gets lost.

How Sonik approaches the marketing-sales handoff

Sonik sits where the play meets the phone. Marketing or growth configures the signals: which triggers matter, which personas, which lists, and the rules that push a contact into a calling session.

Reps open the dialer and find the session ready: the contacts, the "why now" for each, and the AI call prep. The parallel dialer gives them up to 5x more conversations in that session, which is the point of the split. Marketing builds the plays, sales plays the game.

Conclusion

Outbound is not run by sales alone anymore, and that is good news for reps. Marketing owns the plays, sales owns the conversations, and the two share one metric: meetings. This week, write down your top three plays on one page each, with the trigger and the handoff rule, and agree a 24-hour call SLA on every reply.
