Embeddable subscribe forms
Build a subscribe form in the admin, get back an iframe snippet, a JavaScript popup snippet, or a static HTML form — whichever fits your site. Forms POST back to AcelleMail’s frontend route directly; no third-party form-host service in the middle. Custom fields, tags, and the double-opt-in flag are all per-form settings.
Double opt-in by default
Lists ship with subscribe_confirmation on. New subscribers get a confirmation email; only confirmed addresses become “subscribed.” The legal default for GDPR-friendly consent and the deliverability default for senders who want clean reputation. Toggle off per-list if you’re importing pre-confirmed contacts.
Tag & custom-field segmentation
Tag subscribers by signup source, paid tier, location, content interest. Custom fields hold any structured data your form collected. Segment a campaign to tag:paid AND interest:tech; build automations that branch off any combination. The same tag layer drives win-back triggers when a subscriber is tagged inactive.
One-click unsubscribe
Every campaign template auto-injects an unsubscribe link tied to the recipient + campaign. One-click drops the subscriber to unsubscribed — no second confirmation step, the way Gmail & Yahoo bulk-sender rules require since 2024. Unsubscribe events are logged per campaign for the report.
Per-campaign reports
Open rate, click rate, click map, top-domain breakdown, bounce + complaint detail, unsubscribe log. Reports are public-link-shareable per campaign so you can share the numbers with sponsors or co-authors without granting them admin access. No third-party analytics vendor; the data lives in your database.
Bring-your-own SMTP
Amazon SES, SendGrid, Mailgun, Postmark, Postal, raw SMTP — whichever vendor fits your reputation strategy. New vendors ship as a one-class sending-driver plugin. DKIM / SPF / DMARC validation runs against the sending domain regardless of provider; same warmup pacing rules apply per IP.
