Resend a Privy email to people who did not open it

Your sale email went out on Tuesday and most of the list never opened it. The resend that could win them back needs a segment, a copy of the email and a new subject, and it is easy to skip.

Cotlet does it in your own Privy account with list_campaigns, create_segment, duplicate_campaign and send_email_campaign, called by your AI agent, an n8n workflow or a script.

Can Privy do this on its own?

Privy's API and read-only MCP list campaigns and segments but create neither (checked 23 Oct 2026). Privy's help center describes the resend as a manual routine: build the segment, duplicate the email, change the subject and schedule it.

How you do it in Privy today

  1. Open Contacts > Segments, click Create Segment, name it, pick Did not open > a campaign in the Choose category dropdown, select the campaign and click Create.
  2. The dropdown lists campaigns by name, not subject line, so a campaign with a vague name is renamed first: open it under Campaigns and edit the name in the upper left.
  3. In Campaigns, open the menu beside the original email, choose Duplicate, and in the To field select the new segment.
  4. Change the subject line. Privy's guide suggests lines such as "In case you missed it:".
  5. Send or schedule the copy 2 to 3 days after the original, not within 24 hours and not after more than a week.

How to resend a Privy email to people who did not open it

Prompt

Find the October sale email, make a segment of contacts who did not open it, copy the email with the subject "In case you missed it: our October sale", and schedule it for Thursday at 10:00.
  1. 01

    Find the original and check its age

    Your agent reads list_campaigns with status sent and matches the title and send date. If it went out less than 24 hours ago or more than a week ago, the agent stops and tells you, because Privy advises a resend 2 to 3 days later.

  2. 02

    Build the segment

    create_segment adds one condition, Email Engagement, Did not open, with the exact campaign name. Privy cannot edit conditions later, so the agent checks the name against list_campaigns first and reports the mailable_count it gets back.

  3. 03

    Copy the email

    duplicate_campaign copies the design, sets the new subject and points the To field at the new segment. The copy stays a draft and reaches no one. The body is unchanged, which Privy says is fine, but you edit it in the Privy editor if the offer changed.

  4. 04

    Schedule it

    send_email_campaign sets the day and time from your prompt. You confirm the call by default, and the audience is fixed when you do.

  5. 05

    Report what is queued

    The agent returns the segment size, the new subject and the send time, so you can stop it with unschedule_campaign before preparation starts.

What you get back

Example data

Original: October sale announcement, sent Tue 20 Oct, 4820 delivered, 1930 opened
Segment: Did not open October sale, 2890 mailable
Draft: October sale resend, subject "In case you missed it: our October sale"
Scheduled for Thu 22 Oct, 10:00, after your OK

Other ways to ask

  • Resend last week's newsletter to non-openers on Monday morning, only if it was sent 2 or 3 days ago.
  • Make the Did not open segment for my last 3 campaigns, but do not copy or send anything.
  • Resend to non-openers and exclude the Current Customers smart segment.

What Privy allows, and what to know first

  • A Privy segment is dynamic: contacts join and leave as they meet its conditions, but the audience of a campaign is fixed when you approve the send.
  • Privy cannot edit the conditions of a segment after it is created, so a wrong campaign name means a new segment.
  • Privy tracks opens with an invisible image and counts no open when the recipient's client blocks images, so some people who read the email still land in Did not open.
  • A contact who sits in more than one selected segment receives the email once.
  • Privy warns against retargeting unengaged contacts after every campaign and recommends the resend for big sales, drops and brand updates.

send_email_campaign asks for your OK by default. To run it on a schedule without you, switch confirmation off for that tool in your dashboard.
