Email Mailing & Campaigns

FastLinkIt's email mailing feature lets you compose and send branded email campaigns to your contacts and groups. Write in HTML or Markdown with live preview, personalise each message with recipient placeholders, and track delivery status in real time. A branded header with your logo and a footer with an unsubscribe link are added to every email automatically.

Yes. You can use placeholders such as {{"{{Name}}"}}, {{"{{Email}}"}}, {{"{{FirstName}}"}}, {{"{{LastName}}"}}, and {{"{{Company}}"}} anywhere in your subject line or email body. Each placeholder is replaced with the corresponding contact data when the email is sent.

FastLinkIt automatically detects bounced emails and suppresses the affected contacts from future mailings. Bounced recipients are marked as "skipped" in delivery reports so you always know why a message was not delivered.

Every email includes a self-service unsubscribe link in the footer, compliant with RFC 8058 one-click unsubscribe. Recipients can unsubscribe from a specific group or from all future emails. A List-Unsubscribe header is also included so email clients like Gmail and Outlook show their native unsubscribe button.

FastLinkIt supports SMTP, Brevo, and SendGrid as delivery providers. Administrators can configure which provider to use for each email category (Identity, Booking, Mailing, Test) from the admin settings panel. You can switch providers at any time without changing your email content.

FastLinkIt does not impose a hard per-email limit. Your sending capacity depends on the limits of your configured email provider (SMTP server, Brevo, or SendGrid plan). The mailing feature is available to Starter, Basic, Professional, and Unlimited subscribers.

Yes. Toggle A/B test on the compose page to split your campaign into 2–4 variants. Choose the sample size (default 20% of recipients) and a winner-pick window (1 to 24 hours). FastLinkIt sends the variants to the sample, picks the winner by open rate (with click rate as the tie-breaker) once the window closes, then ships the winning variant to the remaining recipients automatically.

Yes. The compose page has a Schedule for later field that accepts any future date and time. The mailing is held with status scheduled until the moment arrives, then transitions automatically to the send queue. You can clear the field any time before send to revert to immediate sending.

Yes — Professional and Unlimited org plans can verify a custom sender domain (e.g. news.acme.com). FastLinkIt generates the SPF, DKIM, and DMARC records you publish in DNS, runs a live verifier against each, then ships every campaign from your verified address with a 2048-bit DKIM signature against your reputation. Available on the /organization page once the subscription is active.

Yes. Register a webhook endpoint at /payments/webhooks and subscribe to any combination of contact.created, contact.updated, contact.unsubscribed, contact.bounced, mailing.sent, mailing.opened, mailing.clicked. Every payload is HMAC-SHA256 signed with your registration's secret (X-FastLinkIt-Signature header), and the registration is auto-disabled after 10 consecutive delivery failures so a broken receiver never backs up the queue.

Yes. Drop one <script> tag on any site with a data-group attribute pointing at one of your contact groups. The hosted widget renders a self-contained signup form, validates client-side, and POSTs to /api/subscribe — anonymous, rate-limited, CORS-friendly. New signups upsert into your contact list with a source:subscribe tag and trigger any drip sequence wired to that source.

Yes. Build multi-step sequences at /mailing/sequences triggered by tag added, group joined, anniversary (birthday or sign-up date), purchase, or first mailing click. Each step has its own delay (in hours) from the previous step. Curated prefabs ship for the most common patterns: birthday email, welcome series (3 steps over a week), post-purchase follow-up (thank-you + review request 3 days later).
