How do I continue an earlier conversation in a new campaign?
Short answer: in the new campaign, turn on Continue an earlier conversation, pick the finished campaign, and add the same mailboxes. Write only the body of step 1. The subject is filled in for you.
A finished campaign can hand its conversations to a new one. Each person's first email in the new campaign goes out as a reply in the thread they already have, from the same mailbox that wrote to them before. WarmySender runs outreach on autopilot with AI agents across cold email, email warmup, LinkedIn, Instagram and multichannel.
From Q3 outreach to a Q4 check-in
You finished a campaign called Q3 outreach. Weeks later you want a Q4 check-in that lands in that same conversation, not as a stranger with a new subject line.
- Create a campaign named Q4 check-in.
- On Sending, turn on Continue an earlier conversation.
- Choose Q3 outreach under Earlier campaign. Only campaigns that have already sent appear in the list.
- Add the mailboxes that sent Q3 outreach. If one is missing, the page names it: Add these mailboxes so everyone can be continued.
- On step 1, write the body only. The subject shows Re: (earlier subject) — set automatically.
- Launch. Each mailbox still sends inside its own limits.
The contact who got "Quick question about your Q3 plan" from [email protected] sees Re: Quick question about your Q3 plan in that same conversation, from Alex, with your new Q4 note underneath.
Who is held back, and how to fix it
After you save, the campaign tells you how many contacts have an earlier email and will be continued, and how many will be held back. Open the Prospects tab to see why each person was held back.
- No earlier email to this contact in the campaign you're continuing. They were never emailed. Leave them held back, or use a separate campaign for a first email.
- The mailbox that emailed them before isn't in this campaign. Add that mailbox and save. Those contacts go back to waiting. Adding the mailbox does not send immediately.
- The mailbox that emailed them before has been removed. Those contacts can't be continued from a different mailbox; start a separate campaign for them. A mailbox that is only disconnected is not a hold: those contacts wait until you reconnect it.
Sends stay inside each mailbox's limits
Continuing a conversation only chooses which mailbox and which thread. Every email is still paced inside that mailbox's daily limit, the campaign's own limit, and the gradual ramp. An agent can create and launch the campaign. It never sends a message itself and can never raise a limit.
Ask an agent
Claude, ChatGPT, Cursor, Codex, OpenClaw, Hermes Agent, or any agent that speaks MCP can do this in plain language. Try: Create a campaign that continues my Q3 outreach conversation. Connecting and disconnecting mailboxes stays in the app.
Questions
What does the person actually see?
They see a reply in the conversation you already had with them, from the same person who emailed them before. The subject is the earlier one with Re: in front.
What if this campaign never emailed someone?
That contact is held back. The Prospects tab says: No earlier email to this contact in the campaign you're continuing.
What if the old mailbox is not on this campaign?
Add that mailbox in Sending and save. Those contacts are picked up again. Nothing goes out the moment you add it.
What if that mailbox was removed or disconnected?
If it was removed, those contacts are held back and can't be continued from another mailbox. If it is only disconnected, reconnect it on the Mailboxes page and they go out once it is back. We never switch them to a different mailbox.
Can I ask an agent to set this up?
Yes. Say: Create a campaign that continues my Q3 outreach conversation. The agent never sends a message itself and can never raise a limit.
Can I change this after the campaign has sent?
No. Once the campaign has sent, the switch is locked. Duplicate the campaign if you want a fresh setup.
