Will my emails actually land in the inbox?

On Scale, yes. Custom-from DKIM-verified domain plus auto-injected business address plus an unsubscribe link in every email. On Growth and Free, alerts ship from a shared Slingshot domain, which is fine for low volume, though Scale is recommended above 1,000 alerts a month.

How do unsubscribes work?

Every email includes an unsubscribe link in the footer. Unsubscribed shoppers are removed from future alerts immediately.

Can I send emails in multiple languages?

Yes. Free includes 1 customer locale, Growth includes 3, Scale includes unlimited. Templates and copy are translated per locale.

Email alerts

Back-in-stock email alerts that look like you sent them.

Q: Can I customize the email templates?

Yes on Growth and Scale. Eight templates ship out of the box: three free (Clean, Minimal, Streetwear) plus five premium industry designs (Fashion, Beauty, Jewelry, Supplements, Home). You can edit subject line, body, colors, and logo without code. Free uses the templates as-shipped.

Slingshot sends back-in-stock email alerts from your own domain with DKIM verification, eight pre-built templates, and auto-injected business address for CAN-SPAM and GDPR compliance. Email is included on every plan, starting with 50 free alerts a month.

Eight templates, fully customizable

Eight templates: three free (Clean, Minimal, Streetwear) plus five premium industry designs (Fashion, Beauty, Jewelry, Supplements, Home). Each template is built for back-in-stock specifically: product image, name, price, single CTA. On Growth and Scale, customize subject line, body, colors, and logo to match your brand. No code required.

Custom-from domain with DKIM (Scale)

Scale plans include a custom-from email domain so alerts come from yourdomain.com instead of a shared sender. DKIM verification meaningfully improves inbox placement. Setup is a single DNS record.

Compliance baked in

Business address auto-injected in every email footer for CAN-SPAM (US), CASL (Canada), and GDPR (EU). An unsubscribe link in every email. Slingshot sends through Resend.

Per-alert revenue attribution

Every email is tagged with a unique link so revenue attribution is automatic. See which template, audience, and time-of-day earn the most revenue per send.
