A cold email stack is the set of tools you use to prepare leads, send relevant outreach and handle replies.
Typical components
- Domains and mailboxes: your sending identity and inboxes.
- Lead sourcing: finding companies and people who fit your offer.
- Verification: checking contact data before sending.
- Sequencer: managing messages, follow-ups, schedules and replies.
- CRM or tracking: recording interested prospects and next steps.
sending.ac supplies the mailbox infrastructure and managed domain setup. It is not a replacement for your sequencer, a lead-list provider, or a service that runs campaigns for you.
Choose tools that fit your workflow and integrate with your existing accounts. Check mailbox capacity, workspace access and integration requirements before adding a new platform. Avoid adding tools that solve the same problem without a clear benefit.
