Number of Seats/Users: InboxGuard offers discounts based on the number of users or seats. A higher volume typically leads to a better discount structure, especially for enterprise-level usage.

Commitment to a Long-Term Contract: Discounts are often provided to companies that commit to using the service for a longer period (e.g., 1-year or 3-year contracts). A longer commitment shows InboxGuard that the company is serious and willing to invest in the platform long-term.

No Active Discounts: Companies that are not already receiving other active discounts may have a better chance of qualifying for additional discounts from InboxGuard. InboxGuard reserves discounts for new customers or those not currently under promotional pricing.

Volume or Usage Commitment: InboxGuard offers discounts if you agree to a minimum amount of usage or transaction volume. This could be based on data storage, transactions, or other metrics tied to how much you will use the platform.

Enterprise-Level Negotiation: Companies that qualify as “enterprise” due to their size or complexity (e.g., having large teams, multiple departments, or geographical presence) may be eligible for additional discounts from InboxGuard. Such companies are often in a position to negotiate for better pricing.

Early Renewal or Prepayment: InboxGuard often offers discounts if you renew early or prepay for the entire contract period. This is a common approach to securing a lower price.

Here at Spendbase our internal data shows that InboxGuard (Retruster) is seen as a “set it and forget it” layer of protection that users quickly grow to rely on.

Key satisfaction drivers our clients highlight:

• Strong phishing and scam blocking
• Very low effort to deploy and manage
• Clear, non-intrusive alerts inside the inbox
• Peace of mind for both IT and non-technical staff

From Spendbase clients’ feedback, three themes stand out:

1) Security & risk reduction
– Many clients mention:
– Blocking sophisticated phishing, credential theft, and ransomware attempts
– Dramatically fewer risky clicks by employees
– Confidence that financial or sensitive emails are genuine
– Several IT leaders say InboxGuard became a “critical part” of their email security stack rather than a nice-to-have.

2) Ease of use & adoption
– Our internal data shows that:
– Setup through Microsoft 365 is quick, with no need to disable existing security tools
– End users don’t have to change their behavior much; the tool runs in the background
– Color-coded warnings and simple messages make it friendly for non-technical staff
– This low friction is a big reason renewal intent is very high among our Spendbase clients.

3) UX details & minor gaps
– Common positives:
– Lightweight, no performance drag
– Clear visual cues on suspicious emails
– Recurring “nice-to-have” requests:
– Ability to customize warning colors
– Option to customize alert text and PDF reports
– Clarification that it’s focused on phishing, not email archiving

From a Spendbase discount and optimization angle:

• Clients consistently perceive strong ROI because:
• Reduced risk of costly breaches and ransomware
• Lower IT support time spent on phishing incidents

• Better board-level reporting on phishing protection success

• When we negotiate InboxGuard pricing, we typically focus on:

• Multi-year commitments for better per-seat rates
• Tier-based discounts as user counts grow
• Bundling opportunities if the client is investing more broadly in security tools

Overall, our internal data shows InboxGuard is best suited for organizations that want powerful, low-friction phishing protection with clear user guidance, and are okay with a focused feature set rather than an all-in-one email platform.
