Honestly: who is better at what
No tool wins everything. These are the things Instantly does better, and the things where Colldly leads.
Where Instantly is better
- Unlimited connected mailboxes even on the basic plan. If you need 50 mailboxes for 37 USD, Instantly is unbeatable.
- The largest warm-up network on the market and years of deliverability tuning at huge volumes (hundreds of thousands of emails a month).
- A big ecosystem: integrations, Zapier, community, tutorials, agency features on higher plans.
- Its own B2B database (paid extra) with hundreds of millions of contacts, strong for the US and enterprise.
Where Colldly is better
- Finds the companies itself: Google Maps in 49 countries, business directories, enrichment from the website. In Instantly you buy leads separately and import CSVs.
- The AI writes from facts on each company's website, in English, German, Slovak or Czech. Instantly generates template copy you have to rewrite.
- Address verification is included in the credit price. You keep the bounce rate under 3% without another tool.
- Replies are sorted by intent (interested, question, later, no) and a reply stops the sequence automatically.
- Autopilot adds companies to the campaign every day from a lead list. In Instantly a campaign simply stops when the list runs out.
- EUR pricing with no per-seat fees, support from the people who build the app, no commitment.
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.

Solo: 1 person, 2 mailboxes, ~250 companies a month
Freelancer or consultant
ColldlyStarter 19 EUR
InstantlyGrowth 37 USD + leads (Lead Finder from ~47 USD) + verification ≈ 85 to 100 USD

Switching from Instantly to Colldly
What can be carried over, what you rebuild and how to do it without a gap in outreach. Usually one afternoon.
1
Export your contacts from Instantly to CSV (company, email, website, name) and upload them to a lead list in Colldly. The import maps the columns itself and merges duplicates.
2
Connect the same mailboxes over SMTP and IMAP with an app password. Reputation is tied to the domain and mailbox, not the tool, so you lose nothing.
3
Carry over the blocklist and unsubscribes: export from Instantly, import into the Blocklist. People who opted out must not get an email from the new tool either.
4
Rebuild the sequence: either templates with variables (your own copy) or let the AI write from website facts. Run both tools in parallel for two weeks and compare reply rates.
Who should pick which
Pick Instantly if
- You send hundreds of thousands of emails a month to the US market
- You need dozens of mailboxes on the cheapest plan
- You can source leads yourself and write or rewrite the copy
Choose Instantly if you run very high volumes with your own lead lists and need unlimited mailboxes on the cheapest plan.
Pick Colldly if
- You contact local SMEs in the UK, Ireland or the EU
- You want one tool from finding the company to the reply in your inbox
- The AI should write from the company's website, not from a template
- You want EUR pricing without per-seat fees
Verdict
If you want one tool that finds the companies, verifies them and writes to each one from what it found on their website, Colldly saves you a whole intermediate step. In Instantly you would buy leads elsewhere, import CSVs and rewrite the AI copy.
Instantly makes sense if you send in huge volumes, already have your own lead source and need to connect dozens of mailboxes on the basic plan.
What it looks like in Colldly
Campaign, sequence, AI copy and replies in one place. No switching between tools for data, copy and sending.
Common questions
Can I move a campaign from Instantly to Colldly?
Contacts yes (CSV export and import into a lead list), mailboxes yes (same SMTP and IMAP details), blocklist yes. You rebuild the sequence; the AI writes the copy or you use templates with variables.
Does Colldly have warm-up like Instantly?
Yes, warm-up runs automatically in the background with a score per mailbox. The network is smaller than Instantly's, but sufficient for hundreds to thousands of emails a day.
Why does Starter not have unlimited mailboxes?
Starter has 5 mailboxes, Pro 10 and Agency unlimited. At 100 to 400 emails a day, 5 to 10 mailboxes is the safe maximum; more mailboxes without volume buy you nothing.
