QuickMail

QuickMail is cold email and LinkedIn outreach software for founders, sales teams and agencies, billed at a flat monthly rate with unlimited users and senders.

QuickMail runs multi-step outreach to people who have never heard of the sender, by email and on LinkedIn, and stops a lead's follow-ups once an email reply arrives. It is made for outbound prospecting at volume, where every new mailbox has to keep reaching the inbox. The Swiss company behind it trades under the same name and has worked on its delivery safeguards since 2014. Campaigns are the core: a series of email steps with waits between them, plus LinkedIn connection requests, messages, InMail and voice messages. Text messages go out through a Twilio account the customer connects. Inbox Rotation spreads sending across connected mailboxes, each held to its own daily limit, while AutoWarmer raises warm-up volume gradually. Liquid syntax personalises each email from lead properties and tags, and email variations are compared on opens, clicks and replies. Reword with AI rephrases step copy, Draft with AI answers from the thread, and an unsubscribe puts the lead on the Do Not Contact list. The product suits founders who prospect for themselves, small sales teams and lead generation agencies working for several clients. Every plan includes unlimited email senders, LinkedIn accounts and users, so a team pays a flat monthly rate set by contacts and sending volume rather than by seats. The API starts on the Growth plan. Agencies move to the Agency plan for separate client workspaces, webhooks and AI sorting of incoming replies, and every plan opens with a trial. A typical campaign pairs a LinkedIn connection request with a run of emails to the same lead, spaced by wait steps. Leads and replies flow into Pipedrive through a two-way sync, or into HubSpot, where sent emails are logged against the contact. Teams on Salesforce log activity there by BCC, and a booked Calendly meeting marks the lead as Booked. The result fits a sender who needs many inboxes working at once without being filtered as spam.
