How to Cancel Gmass: Complete Guide

What is Gmass

Gmass is a Gmail-based mail merge and mass-email service that operates as an extension and SaaS layer on top of Gmail to send personalised campaigns, sequences and high-volume messages from Google accounts. The platform advertises features such as mail merge, address verification, A/B testing, API access and team plans, with tiered subscriptions for individual and organisational use. Gmass publishes tiered pricing (monthly and annual) and a range of team seat counts on its official site; it also states that subscriptions remain active until explicitly cancelled and that some capabilities vary by plan.

Note: the site lists prices in US dollars and recent announcements indicate pricing adjustments effective January 2026. AUD conversions above are approximate, calculated using exchange rates published at the start of January 2026. See the official pricing page and the pricing announcement for exact USD amounts and recent changes.

Customer experiences with cancellation

What users report

Public reviews show polarised experiences: several users report prompt refunds and cooperative support, while a substantial portion report difficulties obtaining refunds, ongoing charges after they believed they had cancelled, and slow or limited support responses. Trustpilot and other review platforms contain multiple complaints about continued billing after cancellation and unexpected restrictions on accounts.

Gmass’s own documentation emphasises that a subscription remains active until the vendor's documented cancellation procedure is followed and that uninstalling the extension does not cancel billing. The terms also describe a formal approach to chargebacks and state that the company will investigate and defend legitimate charges.

Recurring issues and practical takeaways

• 1. Continued charges after an attempted cancellation: multiple reviewers allege recurring charges despite attempting cancellation; retain precise billing records if this occurs.
• 2. No automatic cancellation on uninstall: Gmass documentation warns that uninstalling the extension does not stop billing; account-level action is required.
• 3. Refund outcomes are case-by-case: Gmass states refunds are not automatic and are reviewed individually, so decisions may vary by circumstance.
• 4. Chargeback handling: the provider discloses an investigation procedure and will submit evidence where appropriate; chargebacks can trigger account and merchant actions.

How cancellations typically work for Gmass subscriptions

Framework: Gmass treats subscriptions as recurring services that continue until an authorised cancellation instruction is processed. Consequently, access is normally maintained for the remainder of the paid billing period after cancellation is recognised. This aligns with the platform’s published guidance that cancellation will take effect at the end of the current monthly or annual term.

Billing cycles and proration: Gmass’s documentation and pricing model indicate distinct monthly and annual billing cycles. The provider’s public materials do not promise pro rata refunds as a standard; annual plans are described with fixed-year billing and monthly plans renew monthly. Refunds are discretionary and reviewed individually, rather than guaranteed as an automatic pro rata adjustment.

Cooling-off and statutory rights: under Australian consumer law digital subscriptions have specific interactions with consumer guarantees. If a digital service materially fails to deliver as described, a remedy such as a refund or replacement may be available. However, entitlement to a refund will depend on whether the supply breached a consumer guarantee or was otherwise misleading. Any assessment of a statutory right should reference the facts of the subscription and the provider’s conduct.

Chargebacks and disputes: Gmass’s public policy notes that cardholder chargebacks will be investigated and defended when appropriate. From a contractual perspective, a unilateral chargeback may not immediately resolve the underlying subscription status and can provoke merchant dispute processes. Documentary evidence will be important if a dispute is raised.

Documentation checklist

• Transaction record: payment date, amount, card or payment method descriptor, transaction ID.
• Subscription terms: a copy or screenshot of the plan description, billing cycle and any advertised trial or refund policy.
• Cancellation evidence: date-stamped contemporaneous notes of the cancellation attempt, confirmation messages if received, and the account identifier used.
• Billing statements: bank or card statements showing the recurring charge dates and amounts.
• Support interactions: dates and summaries of any correspondence with support, and ticket/reference numbers where available.
• Feature failures: records showing the service failed to perform as promised, if seeking a remedy under consumer guarantees.

Practical pitfalls and legal implications

Contractual terms govern most disputes: Gmass’s terms of use set expectations about cancellation process, refund discretion and handling chargebacks. In a dispute, the published terms are a starting point but are subject to operation of statutory consumer protections where those protections apply.

Delay in following provider procedures increases risk: where a vendor requires a specific procedure to recognise cancellation, failing to follow that procedure can lead to continued renewal charges. Maintain contemporaneous evidence of your actions and dates if you later contest charges.

Chargebacks carry commercial and evidentiary consequences: merchants typically oppose chargebacks with documentation; a merchant defence can reverse a provisional credit and result in an adverse outcome for the cardholder. Be prepared to supply the documentation checklist items above when disputing a charge.

What to do after cancelling Gmass

Monitor billing statements for two full billing cycles after the effective cancellation date and reconcile each entry against the documentation checklist above. If unexpected charges appear, gather the records listed in the checklist and prepare a concise chronology of events for any third-party dispute process or regulator inquiry.

If a refund is sought for a service failure, frame the request in terms of contractual breach or statutory consumer guarantee failure: identify the promised feature, the factual failure and the remedy sought. Keep requests factual and evidence-based to assist any internal review.

Escalation options: if a reasonable dispute resolution with the provider is unavailable, consider raising the matter through your card issuer’s dispute procedures or a relevant consumer protection agency. Be aware of timelines for chargeback claims and regulator complaints and ensure your documentation supports the factual narrative. Note that chargebacks are a distinct mechanism from statutory complaints and may have different evidentiary thresholds.
