How do I select a specific ConvertKit list to verify?

ConvertKit does not have traditional lists. Its subscribers live in a single pool, then get organized by tags, forms, and sequences. Valid Email Checker maps these to selectable list-like options in the picker so you can verify any meaningful subset. Setup details are in the ConvertKit integration guide.

Opening the picker

1. Open Integrations in the VEC sidebar.
2. Locate the ConvertKit row in Connected Integrations.
3. Click the three-dot menu and pick Sync Now.
4. A modal opens with the ConvertKit logo at the top.
5. Pick one row with the radio button.

What you can verify

• All subscribers — your entire ConvertKit subscriber base.
• Tagged groups — subscribers carrying a specific ConvertKit tag.
• Form-defined groups — subscribers who came in through a specific signup form.

Sequences are not selectable as a list type. If you want to verify subscribers currently in a sequence, build a tag for that sequence in ConvertKit (using their automation rules) and verify the tag instead.

Sizing the verification cost

Each row in the picker shows the subscriber count from the ConvertKit API. The credits-needed line at the bottom updates the moment you make a selection. Duplicate removal (on by default) lowers the actual spend, and unknown-status results are credit-refunded automatically. A 50,000-subscriber tag verification typically costs less than 48,000 credits in practice.

Refreshing list data

Click the circular refresh icon at the top of the modal. VEC re-queries ConvertKit and updates the picker. Use this after creating new tags or running large imports in ConvertKit.

After picking the list

Choose Verify Only or Clean List Automatically below the picker. Verify Only is the default. Clean List Automatically activates the per-category settings — and on ConvertKit, Delete is not in any dropdown because the platform does not expose the operation.

Troubleshooting selection

• Tag missing — your ConvertKit API Secret may be the older v3 key. Both v3 and v4 work with VEC, but a regenerate sometimes refreshes scope.
• Empty picker — the ConvertKit account has no subscribers, tags, or forms yet, or the connected key lacks read access.
• Subscriber count looks low — ConvertKit reports active (confirmed) subscribers only. Pending double-opt-in subscribers are not counted in the picker.
