Email captureLive

Collect emails. Keep them.

Ask for an address in a Lead Flow DM or on your Link in bio page. Each address is kept with the consent it was given under, and you take the list wherever you like.

Capture is live. Direct sync to Kit, Mailchimp or Klaviyo is not available.

Answers

Ask. Keep. Take it out.

Three steps, with the third one stated honestly.

  1. 1

    Ask for the email

    Add an email question to a Lead Flow, or an email capture block to your Link in bio page. Two doors, two lists.

  2. 2

    Keep it with its consent

    A Lead Flow address is kept as a lead with a stage, tags and the consent prompt it used. A Link in bio address goes to your page's subscriber list with the consent text and time.

  3. 3

    Take the list out

    Export either list as CSV. Lead Flow leads can also go to your own endpoint by webhook or be read through the API. There is no Kit, Mailchimp or Klaviyo sync.

Consent

Ask once, on the record.

A Lead Flow only asks for an email using the stored consent prompt. The prompt is kept with the lead, so when someone asks where you got their address, you can show them. On Link in bio the visitor ticks a consent box before the address is saved, and the text they agreed to is stored with it.

  • The prompt is shown before the address is taken
  • The prompt is saved with the lead
  • On Link in bio the visitor ticks a consent box first
  • STOP ends the conversation at once
  • No message carries an emoji

Webhook and API

Send it anywhere.

On Pro and Business, every new Lead Flow lead (a delivered link or a saved email) can be posted to an endpoint you control the moment it is captured, signed with HMAC-SHA256 and retried if your endpoint is down. Link in bio subscribers are not sent by webhook; export them as CSV.

Prefer to pull? The API and the MCP server list and export your leads with the lead flows scope.

What you get.

  • Two doors, two lists

    Lead Flow addresses become leads with stages and tags. Link in bio addresses go to your page's subscriber list with the consent they ticked.

  • Consent on file

    A Lead Flow stores the consent prompt with each address. Link in bio stores the consent text, time and source.

  • Stages and tags

    Each Lead Flow lead carries a stage and your own tags, so a list is already half sorted.

  • CSV export

    Both lists export to a file any spreadsheet and most email tools can open.

  • lead.captured webhook

    A signed event for every new Lead Flow lead, on Pro and Business.

  • API and MCP

    List and export Lead Flow leads from your own code or an assistant, with a scoped key.

Ask us anything.

How do I capture emails from Instagram comments?

With a Lead Flow. Someone comments your keyword, gets your private reply, and an optional email question asks for their address using a stored consent prompt. The address is kept with the lead. Lead Flows is rolling out while Meta's messaging review completes. The email box on your Link in bio page works today: visitors tick a consent box and each address is saved with that consent on your page's subscriber list.

Can I send leads to Mailchimp, Kit or Klaviyo?

Not directly. Blendin does not sync to Kit, Mailchimp or Klaviyo. What you can do today is export either list as CSV and import the file. For Lead Flow leads you can also send each new lead to your own endpoint with a lead.captured webhook (Pro and Business) or read them through the API.

Will Blendin add a direct Kit, Mailchimp or Klaviyo sync?

It is not built, and we do not give dates for things that are not built. The honest options today are the CSV export and, for Lead Flow leads, the lead.captured webhook and the API.

How do I export my leads?

For Lead Flow leads, open your leads, filter by stage, tag or whether they left an email, and export the list as CSV. For Link in bio, export your page's subscriber list, which includes the consent text and time. Both files open in any spreadsheet and import into most email tools.

Does Blendin store consent for the emails it collects?

Yes, for Lead Flows: the email question is only sent with a stored consent prompt, kept with the lead. On Link in bio the visitor ticks a consent box and the agreed text is saved with the address. What consent you need depends on where your audience lives, so check the rules that apply to you.

What does the lead.captured webhook send?

For Lead Flow leads, a signed POST with the event type, the time, and the lead: the lead id, the account id, the trigger (link delivered or email captured), the username, the email, the tags and the capture time. It is signed with HMAC-SHA256 and retried on failure.

Which plans can use webhooks and the API?

Webhooks: Free 0, Creator 1 (post.published, post.failed and webhook.test), Pro 5 and Business 20, with every event including lead.captured on Pro and Business. API keys: Free 0, Creator 2, Pro 5 and Business 10. MCP over OAuth works on every plan.

Can I collect emails on my link in bio page?

Yes. The email block on your Blendin page at blendin.bio asks for an address with a consent box the visitor ticks. Each address is saved with that consent text and time on your page's subscriber list, which you export as CSV. Those addresses are separate from Lead Flow leads, so they have no stages or tags and are not sent by webhook.

Does Blendin send emails to my list for me?

No. Blendin keeps and exports the addresses people gave you. It does not send newsletters or email campaigns. Use your email tool for that.
