Email collection — own your audience before the next algorithm change

I will say this only once because it is unfashionable and true: the single most valuable thing you can do for your future business is build an email list right now. Today. Before you have time to second-guess it. Your TikTok views can drop 80% next week and you have zero recourse. Your email list does not get rate-limited by an algorithm. It is yours.

Most link-in-bio pages bury the email signup behind a click that redirects out to a third-party form. You lose 60-80% of visitors on the redirect alone. The email-collection block on Linkstacked lives inline on your page — visitor types their email, presses subscribe, you have them. Zero redirects, zero context-switch.

Where to put it

There is a right answer here, and it is not 'at the bottom.' Best slot for an email-capture block is the third visible row, just after your hero CTA. Visitor lands, sees the hero (clicks or doesn't), and is presented with a secondary capture they can give you even if the hero didn't connect.

The wrong slot is dead last, below five other links. By the time the visitor scrolls past everything else, they've already decided whether they're going to act. Asking for their email at the end is asking for it after they've left.

What syncs where

We push captured emails to your downstream tool in real time (within 30 seconds of the visitor pressing subscribe). Native integrations:

• Mailchimp — add subscribers to a chosen list/audience with tags
• ConvertKit / Kit — add subscribers to a form, with optional tag
• Beehiiv — add to a newsletter, with custom field support
• Substack — adds to your free-subscriber list
• Ghost — adds to a label, fires a welcome email if configured
• Mailerlite — adds to a group with tags
• Klaviyo — adds to a profile and list
• Generic webhook — post the email + metadata to any URL of your choice
• CSV export — download manually on demand if you're not on a downstream tool yet

Double opt-in handling

Some jurisdictions (Germany, Austria, parts of the EU) require double opt-in — the visitor must click a confirmation link before being formally added to your list. Linkstacked supports both flows. If your downstream tool requires double opt-in, we'll respect that and pass through the confirmation flow. If it doesn't, we'll do single opt-in but you can toggle on double opt-in from our side for your own peace of mind.

We also support a 'sequence trigger' — when someone subscribes via Linkstacked, we can call a webhook that fires a welcome-sequence email out of your tool. That extra round-trip means new subscribers get value in their inbox within 60 seconds of signing up, while the intent is still hot.

Reading the capture data

The analytics dashboard surfaces three numbers for your email-capture block: (1) page views with the block visible, (2) submission count, (3) capture rate — submissions divided by visible page views. Most pages with a half-decent offer should land at 3-6%. If you're under 2%, your offer or your placement needs work. If you're over 8%, you're crushing it — protect that block at all costs.

We also surface per-source capture rate — your Instagram traffic might capture at 4% but your podcast-show-notes traffic captures at 12%. The podcast traffic is your highest-intent source and worth doubling down on.

Compliance, spam, and the bot question

Every email captured goes through three filters before it hits your downstream tool: (1) syntactic validation (no malformed addresses), (2) bot detection (we drop submissions that look automated — same IP submitting many emails, etc.), and (3) disposable-domain check (mailinator, guerrillamail, throwaway-style domains are flagged). The result is a much cleaner list than you'd get from a raw HTML form.

For GDPR/CCPA: we capture consent metadata at submission (IP, timestamp, page URL, the wording of the consent line) and pass it through to your tool. If a regulator ever asks 'when and how did this subscriber consent', you have the proof.

Plan differences

Email collection is a Grow-plan feature ($9/mo). Below that, you can put a link to an external form (Typeform, Mailchimp embed) but no inline capture. The reason Grow gates it: the bot filtering, GDPR consent metadata capture, and downstream-tool sync are all infrastructure that costs us money to run and we charge accordingly.

Add a block, build a list

Open your editor, hit 'add block', pick 'Email capture'. Write a specific offer (not 'subscribe to my newsletter' — something concrete). Pick your downstream sync target. Save. The block is live within seconds. The hardest part is writing the offer line; the rest is two minutes of setup. Six months from now you'll wish you'd done it six months ago.
