Honestly: who is better at what
No tool wins everything. These are the things Smartlead does better, and the things where Colldly leads.
Where Smartlead is better
- Unlimited mailboxes and unlimited warm-up on every plan; for agencies with dozens of domains it is a cheap sender.
- White label and a client portal under the agency's own domain, which Colldly does not offer yet.
- An extensive API and webhooks, behaviour-based subsequences, spintax and fine-grained deliverability controls.
- A master inbox for hundreds of mailboxes at once with bulk actions.
Where Colldly is better
- Data is included: Google Maps, directories, website enrichment and verification. Smartlead is a pure sender; leads come from elsewhere.
- The AI writes from the company's website in the recipient's language. Smartlead's AI only produces variations and translations of templates.
- Unibox sorts intent and a reply stops the sequence without any setup.
- Autopilot: a campaign that tops itself up from a lead list every day.
- Client workspaces with read-only client access are in Agency at 89 EUR with no per-client fee.
- Support from the authors of the app and EUR pricing.
Price in practice: three scenarios
A price list is one thing, the monthly invoice another. Three typical situations and what you would pay in each, including the data and verification you usually buy separately with the competition.
Indicative monthly prices from public price lists (2026), excluding VAT, with a 5-step sequence. Colldly: Starter 19 EUR, Pro 39 EUR, Agency 89 EUR including data, AI copy and verification; extra credits from 5 EUR per 500. Competitor prices change, check the current price list.
Switching from Smartlead to Colldly
What can be carried over, what you rebuild and how to do it without a gap in outreach. Usually one afternoon.
Who should pick which
Pick Smartlead if
- You are an agency with dozens of domains and need a white-label portal
- You build your own integrations on the API
- Data and copy are solved elsewhere
Choose Smartlead if you are an agency with your own data and a need for a deep API or white label.
Pick Colldly if
- You want data, copy and sending in one account
- You contact SMEs across Europe
- Read-only access in their workspace is enough for your clients
- The price should be predictable, without stacking tools
Smartlead is a sending tool, Colldly is the whole system: data, personalised AI copy, sending and replies. With Colldly the lead hunting and the rewriting of AI copy disappear.
Pick Smartlead for large volumes with your own lead source and a need for white-label client reports and a deep API.
