Ask what outbound costs and you get a plan price. But a working outbound programme has six layers, and teams routinely discover that the sequencing tool they compared on is a third of what they end up paying.
Here is every layer, with real numbers, at three scales.
The six layers
| Layer | What it does | Typical range |
|---|---|---|
| Sequencing | Campaigns, steps, sending | $39–$379/mo |
| Infrastructure | Domains, mailboxes, IPs | $0.80–$9.00 per mailbox/mo |
| Data | Contacts, emails, phone numbers | $29–$799/mo |
| Deliverability | Warmup, placement testing, monitoring | $0–$599/mo |
| Channels beyond email | LinkedIn, calling, WhatsApp | $19–$199/mo each |
| Agency overhead | Whitelabel, workspaces, client separation | $0–$29 per client/mo |
Only the first is what most comparisons look at.
What the vendors charge
Verified figures, so you can build your own model.
Sequencing: Instantly $47 / $97 / $358 with contact caps of 1,000 / 25,000 / 100,000. Smartlead $39 / $94 / $174 / $379. Lemlist $69 email, $109 multichannel, seat basis unclear. Outboundry $39 / $89 / $399.
Infrastructure: Smartlead’s SmartSenders run $3.99–$9.00 per mailbox per month plus $13–$19 per domain per year. Outboundry’s Mailboundry runs $0.80–$2.50 per mailbox depending on IP model and term, with domains from $5.99 a year. Google and Microsoft mailboxes bought through a platform typically run $4–$5 each plus $13–$14 per domain per year. Azure at volume is around $25 per domain per month for up to 50 mailboxes.
Data: Lemlist’s enrichment is $20/mo for 2,000 credits, roughly $0.04 per email and $0.16 per phone. Instantly’s credit plans run $47 to $197+. Outboundry’s Data Pro is $149/mo for 12,000 credits, with 1 credit per verified email, 0.5 for LinkedIn-only and 10 for a mobile.
Deliverability: Smartlead’s SmartDelivery is $49 / $174 / $599 a month. Instantly includes unlimited warmup on every plan but does not publish inbox placement pricing. Outboundry includes warmup and 5 / 25 / 500 deliverability tests by tier.
Channels: Outboundry’s Dialer is $19 / $49 / $99 with numbers at $1.30–$2.30 and calls at roughly $0.04 a minute; WhatsApp is $15 per number per month. Lemlist includes calling and SMS on Multichannel but publishes no per-minute or per-message rate. Standalone LinkedIn tools run roughly $59–$199 a month.
Agency overhead: Smartlead whitelabel is $29 per client workspace. Outboundry includes whitelabel and workspaces in the $399 Agency plan.
Three worked stacks
Solo founder, 2,000 contacts, 20 mailboxes, email only
| Layer | Cost |
|---|---|
| Sequencing | $39–$97 |
| 20 mailboxes + 7 domains | $20–$95 |
| Data, light | $29–$47 |
| Deliverability | $0–$49 |
| Total | $88–$288/month |
The spread is almost entirely whether warmup and placement testing are included or sold separately, and whether the entry plan’s contact cap forces you up a tier.
Small team, 25,000 contacts, 60 mailboxes, email + LinkedIn
| Layer | Cost |
|---|---|
| Sequencing | $89–$174 |
| 60 mailboxes + 20 domains | $60–$290 |
| Data | $149 |
| Deliverability | $0–$49 |
| $0–$199 | |
| Total | $298–$861/month |
This is where the two models separate hardest. A platform with LinkedIn included and infrastructure at $0.80–$2.50 lands near the bottom. A stack of email tool plus LinkedIn tool plus mailbox vendor plus placement testing lands near the top, for the same work.
Agency, 20 clients, 200 mailboxes, 100,000 contacts, multichannel
| Layer | Unbundled | Bundled |
|---|---|---|
| Sequencing | $379 | $399 |
| 200 mailboxes + 67 domains | $900 | $160–$500 |
| Data | $149–$799 | $149 |
| Deliverability | $174 | included |
| LinkedIn (20 seats) | $199+ | included |
| Whitelabel (20 clients) | $580 | included |
| Total | ~$2,381–$3,031 | ~$708–$1,048 |
The gap at agency scale is roughly $1,500 to $2,000 a month, or $18,000 to $24,000 a year. Almost none of it shows up in a plan comparison, because it is whitelabel, placement testing and LinkedIn seats, three things priced as add-ons by some vendors and included by others.
The four costs nobody budgets
The tier cliff. Capped-volume pricing means one extra contact can cost you 269%. Instantly’s Hypergrowth-to-Light Speed step is $97 to $358. Know where your boundary is.
Paying for misses. If your data provider charges for lookups that return nothing, a 60% match rate makes your real cost per usable record roughly 1.7x the advertised rate.
Warmup at scale. Priced per mailbox by some vendors. At 200 mailboxes, a per-mailbox warmup charge can exceed the mailbox cost itself.
Rebuilding when you switch. No tool in this category imports sequences from another, so a migration costs a fortnight of someone’s time. Factor that into any “we’ll just move later” assumption.
How to build your own model
Five steps, half an hour:
- Count mailboxes at twelve-month scale, not today. Divide by 3 for domains.
- Count contacts at twelve-month scale, and check where the nearest tier boundary sits.
- List every channel you will actually run, and price each separately unless it is included.
- Add agency overhead if you run clients: whitelabel per workspace, extra seats.
- Add the misses, divide your data budget by your real match rate in your segment.
Then compare that number across vendors rather than the plan price.
Bundled vs unbundled: the comparison that matters
Not feature checklists. Three questions.
First: what does this cost fully loaded, at my volume, with everything I need switched on? Build the number yourself from every product page involved. Vendors quote the entry product because that is the number that wins comparison tables.
Second: how many of these products would I be buying anyway? If the answer is one, unbundled wins on price. If it is five, you are paying a coordination tax to the vendor for the privilege of coordinating it yourself.
Third: what does it cost per meeting? Divide the fully loaded monthly number by the meetings the programme books. That is the only figure that lets you compare a $40 entry product against a $400 one honestly, and it is the one that tells you whether outbound is paying for itself. Cost per meeting by channel shows the method.
| Unbundled stack | Connected stack | |
|---|---|---|
| Entry price | Low, per product | Higher, includes more |
| Real cost with AI and data | Often $1,000+ across products | Usually $300–$600 |
| Logins and bills | Four to seven | One |
| Where a lead lives | Split across products | One record, first touch to closed deal |
| Reply to meeting | Handed between products | Same inbox, same record |
| Deliverability debugging | Cross-team triage | One vendor |
| Replacing one component | Easy | Harder |
| Best for | Teams with an existing stack and one gap | Teams building the whole programme |
Where the unbundled model is the right answer
Worth being specific, because this is not a universal argument.
If you have a data contract you are locked into, buy sending alone. If you are an agency reselling infrastructure to clients and want the infrastructure vendor’s brand out of the way, a standalone infrastructure product with a whitelabel is genuinely the cleaner architecture. If you need one very specific capability at a quality no bundled product matches, buy the specialist.
And if you are experimenting, a $40 entry price beats a $400 one for finding out whether outbound works for you at all, even if the $40 is not the real number long term.
The short version
An outbound stack has six layers and the sequencing tool, the one everyone compares, is typically a third of a small team’s bill and a sixth of an agency’s.
At solo scale the range is $88 to $288. At small-team scale, $298 to $861. At agency scale, roughly $700 against $2,400 depending entirely on whether whitelabel, placement testing and LinkedIn are included or sold beside the plan.
Build your model at twelve-month scale, check where the tier boundaries fall, and add the cost of lookups that return nothing. Those three adjustments change which vendor wins more often than any feature comparison does.
Next: which pricing model suits your team, or infrastructure cost at 10, 100 and 500 mailboxes.
Frequently asked questions
How much does an outbound sales stack cost?
Roughly $88–$288 a month for a solo founder, $298–$861 for a small team, and $700–$3,000 for a 20-client agency. The spread at each level comes from whether infrastructure, deliverability testing, LinkedIn and whitelabel are included or priced as add-ons.
What is the biggest hidden cost in outbound tooling?
At agency scale, whitelabel and placement testing. Whitelabel at $29 per client workspace is $580 a month across 20 clients, and placement testing runs $49 to $599, both invisible in a plan comparison.
How many layers does an outbound stack have?
Six: sequencing, infrastructure, data, deliverability, channels beyond email, and agency overhead. Most comparisons only look at the first.
Should I budget for migration costs?
Yes. No tool in this category imports sequences from another, so switching means rebuilding campaigns by hand, roughly a fortnight of someone’s time.
How do I compare outbound tools on cost per meeting?
Add every product the programme needs at your volume, including data, mailboxes, domains and AI, then divide the monthly total by meetings booked. Run it for both options over the same period. A cheaper entry price that books fewer meetings is the more expensive tool.
Is it better to buy outbound tools separately or connected?
Separately, if you already have most of the stack and need one component. Connected, if you are building the programme from scratch, because you will otherwise end up buying the same pieces from the same vendor with more logins, more invoices and more places for replies to go missing.
Why do vendors unbundle their products?
It lowers the entry price, lets each product rank and sell independently, and expands the addressable market to buyers who only want one piece. Those are sound commercial reasons. They are not the same as being cheaper per meeting for a buyer who needs the whole programme.
