Daily new-signup email validation

Every morning, validate yesterday's new signups with ZeroBounce and flag the invalid, role-based, and abuse addresses — so bad emails get caught before they bounce, hurt your sender reputation, or pollute your CRM.

Works with
The instructions
Every day at 8am, validate the email addresses of people who signed up yesterday and email me the ones worth a second look. Validation only — never send email to a signup.

1. Gather yesterday's new signup email addresses (paste the list into the instructions, or read them from the source this routine is connected to). Validate them with ZeroBounce using the batch tool.

2. Split the results into three buckets:
   - "Block / fix" — invalid addresses (mailbox not found, no DNS records) and obvious typos. For typos, show ZeroBounce's did_you_mean suggestion.
   - "Review" — catch-all, role-based (e.g. info@, support@), and disposable/abuse addresses. These often signal low-intent or throwaway signups.
   - "Clean" — valid addresses, just a count.

3. For each flagged address give the email, the status + sub_status, and the suggested correction if there is one.

Lead with a one-line headline: how many signed up, and how many have a deliverability problem. If there were no signups yesterday, say so. Keep it short — I should be able to act on it in under a minute.
What a run emails you
New-signup validation — 30 Jun 2026

47 signups yesterday — 6 need attention (3 to fix, 3 to review).

Block / fix (3)
• liam@gmial.com — invalid, possible_typo → did you mean liam@gmail.com?
• test@asdfasdf.io — invalid, no_dns_entries
• [deleted]@company.com — invalid, mailbox_not_found

Review (3)
• info@acme.co — do_not_mail, role_based
• jordan@mailinator.com — do_not_mail, disposable
• sales@vendor.io — do_not_mail, role_based

Clean: 41 valid addresses.

How it works

  • Attach your ZeroBounce connection (paste your API key on the Connections page). Each morning the routine validates yesterday's signups in a single batch call and sorts them into act-now, review, and clean — so you catch fake or mistyped emails before your welcome flow bounces against them.
  • It separates hard problems (invalid, no-DNS, mailbox-not-found) from soft signals (role-based, disposable, catch-all), because they call for different responses — one is a fix, the other is a judgment call.
  • When ZeroBounce spots a likely typo it surfaces the did_you_mean correction, so a recoverable signup isn't quietly lost. Keep "Email me the result" on to get the digest before you start your day.

Make it yours

  • Point it at your signup source — paste the addresses into the instructions, or connect wherever new signups land so the agent can read them.
  • Adjust the buckets to your rules: some teams auto-suppress role-based addresses, others keep them — tell the routine and it'll sort accordingly.
  • Widen the window to catch a weekend's worth of signups on Monday, or tighten it to the last few hours during a launch.

Your connection stays yours: your API key is encrypted at rest, and ZeroBounce is validation-only — the agent reads deliverability results, it never contacts your signups.
