In about 10 minutes: connect a mailbox, fill in the offer profile (what you sell and to whom), enter an industry and region and Colldly finds the companies, verifies them and writes to them. Check the previews and launch. The only thing that cannot be rushed is warming up a new mailbox (2 to 4 weeks), so connect it right away.
You do not need one. AI search in Colldly finds companies by industry, location and size, just enter what you are looking for. You build the list directly in the tool in a few minutes. If you have your own list, upload it as CSV and the system verifies it the same way.
Colldly works for B2B services, SaaS, agencies, IT companies, consulting, manufacturing and trade. If you sell to companies, cold email works. If you are not sure, try the free plan and decide based on the replies.
Yes. The AI writes in English, Slovak and Czech, you set the language per campaign. The application itself has an SK/EN switch and the website is available in both languages.
1 credit = 1 action in the system. For example: finding a company on Google Maps costs 1 credit (only 0.1 from a business directory), enriching a contact 1 credit, verifying an email 1 credit and generating one email with AI 1 credit. Sending itself is free. You only pay for what you actually use.
The monthly credits included in a plan (e.g. 2,000 credits in Starter) renew with every billing period. Credits bought as credit packs (Mini, Standard, Pro, Max) never expire and stay on your account until you use them.
Yes, you can upgrade or downgrade at any time directly in account settings. An upgrade applies immediately, a downgrade at the end of the current billing period. Cancelling is one click, no phone call.
Yes. After logging in, create an invite link in the Credits and plan section. When someone signs up through it, you both get +200 extra credits. These credits never expire and are not limited by the plan.
Yes, Colldly supports both. You can connect Gmail accounts (including Google Workspace), Microsoft 365 and your own SMTP servers. You can combine several mailbox types in one campaign and the system rotates them.
Warm-up is an automatic process that gradually builds the reputation of a new mailbox. Colldly sends and receives real emails between mailboxes in the network, replies to them and rescues messages from spam into the inbox. It is available from the Starter plan and runs in the background without any work on your side.
Mailbox rotation automatically alternates several email accounts when sending campaigns. No mailbox exceeds a safe daily volume, you avoid provider limits (Gmail, SMTP) and reduce the risk of your emails landing in spam. Available from the Starter plan.
Advanced scheduling lets you set exactly when emails go out: weekdays, a time window (e.g. 9:00 to 17:00), the recipient's time zone and specific dates when the campaign should run or pause. The result is emails that arrive during working hours.
The AI searches publicly available sources: Google Maps, business directories and the companies' own websites. You get the company name, website, email contact and a short description of what it does, without manual research.
Email opens usually appear within 24 to 48 hours of sending. You can expect the first replies after 3 to 7 days once follow-ups kick in. You track results in real time directly in the dashboard.
It depends on the industry, offer and copy quality. The platform-wide average is shown live on the home page, good campaigns run between 3 and 8% replies from contacted companies. With 200 companies contacted a week that means 6 to 16 conversations every week.
The AI writes short, factual emails built on facts from the specific company's website, without filler phrases. You set the tone, length and language, see a preview of every email before sending and can edit it or have it rewritten.
Yes, cold email is legal in B2B communication. Colldly only contacts business addresses from publicly available sources. The system processes unsubscribes automatically and keeps a suppression list, which keeps it compliant with the GDPR. Details are in our guide on GDPR and cold email.
On a server in Germany with encrypted transport. Every account's data is separate, mailbox passwords are encrypted in the database with a separate key and client data is never used to train AI. You can export contacts and results at any time and delete the account yourself.
