Features — Mailyone

Deliverability

An email that ends up in spam does not exist. Mailyone watches what mailbox providers watch.

Domain authentication: SPF, DKIM and DMARC checked before every send, with alerts on regressions.
Sending accounts: Brevo, Mailjet, Amazon SES, SMTP2GO or SMTP, with hourly and daily quotas and load sharing across accounts.
Provider feedback: Bounces, complaints and unsubscribes received in real time through signed webhooks, or read from a bounce mailbox.
Suppression list: Any bounced, complaining or erased address is blocked for all your sends, permanently.
One-click unsubscribe: Compliant with Gmail and Yahoo bulk-sender requirements (RFC 8058).
Tracking domain: Links go through a subdomain in your name: your reputation is shared with no one.

Every contact knows where it came from. Every send checks it is allowed to leave.

Legal bases: Proven opt-in, declared opt-in, customer (soft opt-in), unknown origin: each subscription carries its own.
Purpose of the email: An affiliate offer never goes to a customer without opt-in; a brand offer only goes to that brand's customers.
Records: Exact checkbox wording, date, IP address, browser: stored and exportable for every consent.
Forms: Double opt-in every time, embeddable on your sites, bot protection without captcha.
Imports: Large files uploaded in chunks, address validation, disposable address and typo detection.
Re-permission: A dedicated campaign turns a list of unknown origin into a proven one.

Emails that render properly everywhere, from Outlook to the Gmail app.

Visual MJML editor: Guaranteed responsive layout, editorial templates shipped with the legal footer.
Personalisation: First name, custom fields, order or cart contents, in a sandboxed environment.
Checklist: Subject, preheader, unsubscribe link, postal address, size, images without alt text, risky vocabulary.
Previews and tests: Desktop, mobile, plain text, test sends rendered with a real contact.

The emails that earn the most are often the ones nobody sends by hand.

Triggers: Confirmed subscription, tag, anniversary date, paid order, abandoned cart.
Steps: Waits, emails, conditions, actions on tags and lists.
Safeguards: Legal basis checked again before each email, sending window, one sequence at a time, exit goals.
Templates: Three-email welcome, post-purchase, birthday, win-back, abandoned cart.

A connector designed around the law, not only the API.

Checkout consent: Notice and opt-out checkbox displayed and archived as proof of soft opt-in; partner offers through double opt-in.
Purchase history: Orders, amount spent, latest products, per brand, on both WooCommerce storage modes.
Abandoned carts: Logged-in customers only, signed recovery link, recovered revenue measured.
GDPR: Erasure requests made in WordPress are relayed to Mailyone.

Honest numbers: every rate is computed on the right base.

Campaign report: Hour-by-hour activity, clicked links, results by mailbox provider, CSV exports.
A/B testing: Subject, preheader or sender, random sample, winner sent automatically, significance test.
Dashboard: Complaint rate against Gmail thresholds, subscribers gained and lost week by week.
UTM: Visits and sales attributed in your analytics, without individual tracking.
