Dials that actually connect — and conversations that actually convert

Home › Services › Programmatic Outbound › Cold Calling Playbook

The pattern we see most: a team points their SDRs at a ContactOut export and tells them to dial. Connect rate is 0.5% to 2%. After two weeks, morale collapses and the manager blames the reps. The reps aren't the problem. The list is.

Every piece of the calling motion — data quality, list scoring, dialer choice, regional tuning, and compliance — compounds. Get one layer wrong and dials go nowhere. Get all of them right and cold calling becomes the most efficient channel in your stack.

The list scoring shift

List scoring is the biggest multiplier in cold calling. Two tools dominate this layer:

• TitanX — premium, ~$1,000/month, scores leads on likelihood to answer based on historical connect data. Considered the best. Pricing is the main barrier.
• Sureconnect — integrates with Clay, can run on Clay credits or BYOK. More accessible pricing. Strong alternative to TitanX.

The math: raw US dials on an unscored ContactOut list hit about 0.5-2% connect rate. Dialing a scored list from TitanX or Sureconnect moves that to 20-30%. That's one conversation every 3-5 dials versus one every 50-200. The same SDR who booked 2 meetings a week starts booking 10-15.

Parallel dialers: pick the right one

Parallel dialers dial multiple numbers simultaneously and route the first pickup to the rep. They turn the “sit and listen to rings” problem into a 3-5x productivity multiplier.

TitanX

Premium parallel dialer with built-in list scoring. Best-in-class connect rates, strongest for outbound teams calling US mid-market. Main drawback: price.

Salesfinity, Trellus

Mid-tier parallel dialers with solid deliverability (reducing spam-likely flags on caller ID). Trellus integrates as a Chrome extension over existing tools — useful if you don't want another interface.

Cloudtalk

Traditional cloud phone system with parallel dialing capability. Stronger fit for teams that also need inbound call handling. Works well for UK markets.

Orum, Nooks, Koncert

Enterprise parallel dialers with heavy integration into Outreach and Salesloft. Strongest for ENT teams that already run on those platforms. Higher price points.

Frontspin, Aircall, Dialpad, Kixie, PhoneBurner, Colddialler

The broader dialer ecosystem. Frontspin is frequently praised for deliverability. Aircall is solid for teams of 3+. Colddialler is a newer entrant focused on high connect rates with faster iteration on user feedback. Kixie and Dialpad integrate cleanly with HubSpot.

Regional connect rate reality

Connect rates vary dramatically by region. Plan territory-specific playbooks and dialer choice accordingly. Rough benchmarks from operators running at scale:

Region	Raw connect rate	Scored connect rate	Notes
Australia / New Zealand	8-15%	25-40%	Highest pickup rates globally. Short calendar. Direct-dial culture.
Europe (UK, DACH, Benelux, Nordics)	3-8%	15-25%	Mid-tier. UK highest within Europe. DACH hardest.
United States	0.5-2%	20-30%	Lowest raw rate due to spam flagging; biggest uplift from scoring.
Middle East	6-12%	20-35%	Strong WhatsApp-first preference in UAE, Saudi, Israel.

Catch-work numbers beat personal mobiles

When your phone waterfall returns a mobile number, check whether it's a personal or work mobile. Personal mobiles convert worse (prospects are defensive), carry higher compliance risk, and in the UK specifically expose you to TPS register liability. Work mobiles and direct-dials perform better across every metric.

Waterfall phone enrichment: Cognism is often strongest on European work mobiles. BetterContact has impressive UK coverage. FullEnrich, Apollo, LeadSniff, and Nymeria fill gaps. Layer them.

UK-specific: the TPS register

The UK Telephone Preference Service (TPS) register is a legal suppression list. Making a marketing call to a number registered with TPS is illegal in the UK. Fines range from £500 to £500,000.

Scrub your UK dial list against the TPS register before calling. Most UK phone enrichment providers can do this; if not, use the free TPS checker on their website. Every +44 mobile and landline should be checked.

When prospects flag that they're TPS-registered, have a script ready. The one we've seen work best:

“Oh, I'm sorry about that. We got your number from a data provider — I'd be happy to send you their details. Do you get these calls often? There's a government scheme, the TPS register, that you can sign up to in two minutes to stop cold calls entirely. I'll send you the link after the call. Quick question — is there a work number I could reach you on instead?”

About 25% tell you to get lost. About 75% engage. That's a better ratio than most cold email opens.

Dial caller-ID hygiene

If your outbound number is flagged “Spam Likely” by T-Mobile, Verizon, or AT&T (US), your connect rate collapses no matter how good your list is. Protect caller ID by:

• Using a parallel dialer that rotates outbound numbers automatically (Leadhero, Trellus, Salesfinity, TitanX all handle this)
• Registering your numbers with STIR/SHAKEN if on custom infrastructure
• Warming numbers before heavy dial days — cold calls from a newly provisioned number get flagged faster
• Avoiding local-presence dialing in the US unless you have strict compliance with state TCPA rules

The channel sequence that works

Cold calling in isolation works. Cold calling orchestrated with email and LinkedIn works better. The sequence we build for most clients:

• Day 0: Email 1 (short, pattern-interrupt opener)
• Day 2: LinkedIn connection request with personalized note
• Day 4: Cold call 1 (attempt direct dial, then mobile)
• Day 7: Email 2 (different angle, reference the prior touches)
• Day 10: LinkedIn DM (if connected) or voice note
• Day 14: Cold call 2 (different time of day)
• Day 18: Email 3 (break-up email, straightforward ask)

Calls land warmer when email and LinkedIn have primed the prospect. Prospects who see your name before the call convert at 2-3x the rate of fully cold contacts.

Openers and objection handling

First 15 seconds. That's your window. The best cold call openers we see:

• Pattern interrupt: “Hey [name], this is Noah. I know this is out of the blue — do you have 27 seconds?”
• Honest frame: “Hey [name], this is a cold call. Want me to keep going or hang up?” (Works shockingly well with founders and ops leaders.)
• Reference prior touch: “Hey [name], I sent you a note last week about [topic] — did you see it?”

Common objections and responses:

• “How did you get my number?” — “From a data provider, happy to send you their details. We use it for research on [ICP] looking at [problem].”
• “I'm not interested.” — “Totally fair — quick question so I don't waste your time: is it [problem A] or [problem B] that you're actually solving right now, or neither?”
• “Send me an email.” — “Will do. Before I send it — what's the one thing you'd need to see in it to actually read it?”
• “Now's not a good time.” — “Understood — 15 seconds and I'll let you go: what we do is [outcome]. If that's relevant, I'll send a calendar link. If not, no worries.”

Speed to lead

A warm reply on email that doesn't get a call-back within 5 minutes is worth 70% less than one that does. We automate positive-reply detection into a real-time alert to the rep's phone, and fire a cold call immediately. Meeting links go out if no pickup within 10 minutes.

This is not optional at scale. A 4-hour delay on a warm reply is a lost opportunity.
