Migomail processes every unsubscribe request within seconds — from one-click email header unsubscribes, landing page requests, and reply-to-unsubscribe — suppresses the address globally, and gives you a branded preference centre that reduces full unsubscribes by up to 40%.
A delayed unsubscribe is a guaranteed spam complaint. A missing unsubscribe link is a legal violation. Migomail handles both — processing every unsubscribe method in under 10 seconds and maintaining the complete audit trail regulators require.
Every Migomail email includes an RFC 8058-compliant List-Unsubscribe header with a POST endpoint. Gmail and Outlook show a one-click "Unsubscribe" button directly in the inbox UI — above the email content — that allows subscribers to unsubscribe without opening the email, without navigating to a landing page, and with a single click. Migomail processes these POST requests within 10 seconds.
Every campaign automatically includes a visible unsubscribe link in the email footer — required by CAN-SPAM, GDPR, CASL, and India's DPDP Act. The link text, styling, and footer layout are customisable per template while maintaining compliance. Migomail processes link-click unsubscribes instantly and records the timestamp, source email, and subscriber IP address.
Instead of a binary unsubscribe, show subscribers a branded preference centre — where they can reduce email frequency, update content category preferences, or opt into digest mode. Subscribers who update preferences instead of fully unsubscribing are 4× less likely to mark future emails as spam. Preference centres reduce full unsubscribes by up to 40% on well-designed implementations.
Some subscribers reply directly to an email with "unsubscribe" or "remove me" rather than clicking a link. Migomail monitors the reply address for each campaign, processes reply-based unsubscribe requests automatically, and suppresses the address as if the subscriber had clicked the standard link.
When a subscriber unsubscribes, they are added to the global suppression list that applies across every campaign, automation workflow, and trigger email sent from your account. The suppression check happens at send time — so an unsubscribed address re-added to a list through an import or CRM sync is automatically excluded from the next send.
Every unsubscribe event is logged with the full audit record — subscriber email, unsubscribe timestamp, unsubscribe method (one-click header, link click, reply, manual), source campaign, IP address of the request, and the suppression list addition timestamp. This record is queryable per subscriber and exportable for GDPR Data Subject Access Requests.
When a subscriber who previously unsubscribed attempts to re-subscribe through a sign-up form, Migomail handles the re-subscribe flow correctly — requiring explicit double opt-in confirmation, recording a new consent event, and removing the suppression only after the confirmation link is clicked. This creates a clean consent record that satisfies GDPR re-subscribe requirements.
Your unsubscribe rate is monitored per campaign, per list, and per sending domain. Alerts fire when your unsubscribe rate exceeds configurable thresholds — a campaign-level spike typically indicates a relevance or frequency problem; a list-level trend indicates a list quality or consent issue. Both require different responses and Migomail distinguishes between them.
An unsubscribe is not just a button click — it triggers a chain of system actions that protect you legally, maintain your sender reputation, and update your subscriber data in real time. Here is exactly what happens.
Every major email marketing regulation has specific, enforceable unsubscribe requirements. Migomail meets all of them automatically — so you never have to check compliance manually or maintain separate processes per jurisdiction.
An unsubscribe link that leads to a branded preference centre — where subscribers can reduce frequency, update interests, or switch to a monthly digest — converts 40% of would-be unsubscribers into retained, lower-frequency subscribers.
Update how you'd like to hear from us — or unsubscribe completely if you prefer.
The preference centre is hosted on your own subdomain (email.yourbrand.com) with your logo, brand colours, and typography applied automatically from your Migomail Brand Kit. Subscribers see your brand, not Migomail.
Let subscribers opt in and out of specific email categories — product updates, promotional offers, educational content, event invitations — independently. A subscriber who opts out of promotions but stays subscribed to product updates is more valuable than a full unsubscribe.
Subscribers who find your email frequency too high can switch to a weekly or monthly digest — receiving a curated summary instead of individual emails. This captures subscribers who would otherwise unsubscribe entirely because of volume.
Migomail customers who implement a well-designed preference centre with frequency options see up to 40% fewer full unsubscribes compared to a plain unsubscribe landing page. Subscribers who reduce frequency instead of unsubscribing have 60% higher 12-month retention.
Every update made in the preference centre is logged with timestamp, preference type, old value, new value, and the source URL — creating a complete audit trail of subscriber consent choices that satisfies GDPR requirements for demonstrating lawful basis.
Migomail includes unsubscribe management by default — one-click headers, suppression, and audit trail require no setup. The preference centre and custom branding take under an hour to configure.
Non-compliance with unsubscribe requirements is not a theoretical risk — regulators actively enforce it and the financial penalties are substantial. This is what each regulation says about non-compliant unsubscribe handling.
Feedback from email marketing managers, data protection officers, and compliance leads who use Migomail to handle unsubscribe management correctly.
The preference centre was the single highest-impact change we made to our email programme in 2024. Before implementing it, we were seeing 0.4% unsubscribe rates on promotional campaigns — which sounds low, but on a 200,000-subscriber list sending weekly that is 800 people permanently leaving every week. After setting up the preference centre with a "monthly digest" option, 38% of people who clicked our unsubscribe link chose the digest instead of leaving entirely. Our list size stabilised for the first time in two years and the people who stayed on monthly digest open at 61% — much higher than our weekly send average. The math on retaining those subscribers instead of losing them permanently is enormous.
As a Data Protection Officer, my primary concern with our email platform was the audit trail. Under GDPR, if we receive a Subject Access Request or a regulatory enquiry about whether we honoured a specific subscriber's opt-out, I need to produce documented evidence — timestamp, method, the fact that sends stopped immediately. On our previous platform, I could not produce that evidence without an engineering request. In Migomail I can look up any subscriber, see their full consent history — when they subscribed, when they unsubscribed, what method they used, at what time down to the second — and export it in a DSAR-ready format. The audit trail alone justified the migration. The compliance confidence it gives me on regulator-facing questions is something I cannot put a number on.
Our unsubscribe rate dropped by 31% within two months of switching to Migomail — not because we stopped sending, but because of two specific Migomail features. First, the RFC 8058 one-click header means subscribers who just want to remove themselves do it in one click directly from the inbox — they do not land on a page that accidentally keeps them or that they have to navigate. Clean and immediate. Second, the Migomail preference centre intercepts the subscribers who clicked unsubscribe because of frequency overload — and 42% of those chose the monthly digest instead. Together these two changes fundamentally changed our list retention numbers. The one-click header makes unsubscribing easier. The preference centre makes full unsubscribing less necessary.

Common questions about unsubscribe management and email marketing compliance.
RFC 8058 is an email protocol standard that defines a machine-readable List-Unsubscribe header containing a POST endpoint. When Gmail and Outlook detect this header, they display a one-click "Unsubscribe" button directly in the inbox interface — above the email content — that triggers a POST request to your processing endpoint when clicked. The subscriber unsubscribes without opening the email, without navigating to a landing page, and with a single click. Google began requiring RFC 8058 compliance for bulk senders (5,000+ emails/day) in 2024 — senders without it faced bulk folder routing. Migomail includes an RFC 8058-compliant header in every email automatically.
Within 10 seconds of the request being received — regardless of the unsubscribe method (one-click header POST, link click, or reply processing). The processing timeline: receive request → match subscriber record → add to global suppression list → create audit record → show confirmation. All five actions complete within 10 seconds. CAN-SPAM requires processing within 10 business days; GDPR requires "without undue delay." Migomail's < 10 second processing significantly exceeds both requirements.
A preference centre is a branded web page — hosted on your subdomain — where subscribers can manage their email preferences instead of fully unsubscribing. Options include: toggling specific email categories on or off, switching from individual emails to a weekly or monthly digest, or updating their email frequency. When the unsubscribe link leads to a preference centre instead of a plain confirmation page, subscribers who are clicking unsubscribe due to frequency overload — rather than genuine loss of interest — can reduce their email volume without leaving your list entirely. Migomail customers who implement preference centres with frequency options see up to 40% fewer full unsubscribes.
Yes. Every unsubscribe event is logged with: subscriber email address, unsubscribe timestamp (to the second), unsubscribe method (one-click RFC 8058 header, in-email link click, reply processing, or API/manual), source campaign name and ID, subscriber IP address at time of request, and the suppression list entry timestamp. This record is queryable per subscriber from the subscriber profile view and is exportable in CSV format for GDPR Data Subject Access Requests. The audit trail is retained for the duration of your account.
The address is protected by Migomail's global suppression list, which is checked at send time — not at import time. If a suppressed address is re-imported or synced from a CRM, it appears in your list but is automatically excluded from every campaign, automation, and trigger send. Migomail does not delete re-imported suppressed addresses — they remain visible in your list with a "suppressed" status — so you can identify the source of the re-import and fix the upstream system that is adding them.
Yes, through a proper re-subscribe flow that Migomail enforces by default. When a previously unsubscribed email address submits a sign-up form, Migomail triggers a double opt-in confirmation email. Only after the subscriber clicks the confirmation link is the suppression removed and the address added back to the active list with a new consent record. This is required by GDPR (re-subscribe must demonstrate fresh explicit consent) and produces a clean audit trail showing the original unsubscribe and the new re-consent event separately.
Yes, via webhook. Configure a webhook endpoint in your Migomail settings to receive unsubscribe events in real time — Migomail sends a POST request to your endpoint with the subscriber email, timestamp, and event type within seconds of processing. Most CRM platforms (HubSpot, Salesforce, ActiveCampaign) can receive this webhook and update the contact record accordingly — preventing sales or support teams from emailing unsubscribed contacts from the CRM. Native HubSpot and Salesforce integrations sync unsubscribe status bidirectionally without requiring webhook configuration.
Migomail supports both. A list-level unsubscribe removes the subscriber from a specific list — they may still be on other lists and receive emails from those lists. A global unsubscribe adds the subscriber to the account-level global suppression list — they are excluded from all sends across all lists, all automations, and all trigger emails from that account. The default Migomail unsubscribe link processes a global unsubscribe. You can configure list-specific unsubscribes for specific campaigns if your programme architecture requires it — for example, if you manage separate programmes (a newsletter and a promotional programme) that subscribers should be able to opt out of independently.
