Serif

Serif puts an AI employee in shared email addresses such as info@, support@, and billing@ to handle routine messages. It connects to Google Workspace or Microsoft 365, and can also work with an address of its own. The assistant can qualify and route inquiries, answer common questions, collect paperwork, send quotes, and follow up on unpaid invoices. It escalates ambiguous or sensitive messages to the team, and users can approve replies before allowing it to work independently. The shared inbox page offers $100 in free credits without requiring a credit card, and every plan includes a 7-day free trial with full access. Listed monthly plans include Lite at $30 a month, Standard at $50 a month, Pro at $200 a month, and Team at $50 a month per user. Serif says it is SOC 2 Type 2, GDPR, and HIPAA compliant; it also says emails are not used to train general AI models or stored on its servers. Desktop downloads are available for Mac and Windows, alongside an iOS app; Android is coming soon.

Serif covers several routine shared-inbox tasks while leaving room for team review of sensitive or unclear messages. It offers free credits and a 7-day trial, with desktop and iOS downloads listed.

Serif is intended for small businesses and operations teams that want to automate routine email and document work. It may suit teams using Google Workspace or Microsoft 365 that want to review replies before handing off routine inbox tasks.

Overview

Serif adds an AI employee to shared business email addresses, with workflows that extend beyond drafting replies. It is best suited to small businesses and operations teams handling repeatable requests that still need human oversight when a message is unclear or sensitive. Its appeal is the combination of inbox automation and escalation; the main trade-off is choosing a paid plan whose usage allowance fits the workload.

Key features

Serif can qualify and route inquiries, answer common questions, collect paperwork, send quotes, and follow up on unpaid invoices. That makes it a stronger fit for shared inboxes tied to operational tasks than for teams looking only to polish occasional replies. It connects to Google Workspace or Microsoft 365, and can also work with an address of its own.

When a message is ambiguous or sensitive, Serif escalates it to the team. Users can approve replies before allowing it to work independently, a useful safeguard for teams introducing automation cautiously. Serif says it does not use email to train general AI models or store emails on its servers. It also says learned assistant data is encrypted at rest, email is accessible only to the user and assistant, and data is never sold. Serif states that it is SOC 2 Type 2, GDPR, and HIPAA compliant.

Pricing

The Free plan costs nothing and provides $100 in credits without requiring a credit card. It is a low-commitment way to try the service, but the credit allowance makes it a starting point rather than an ongoing high-volume option. All plans include a 7-day free trial with full access.

Lite costs $30 a month, billed monthly, and includes a meeting recorder, task manager, knowledge base, Serif AI, and email triaging and drafting. It is the lowest-priced paid tier, but does not include the higher usage multiples offered by Standard and Pro.

Standard costs $50 a month, billed monthly, and provides five times Lite usage plus True Voice. It suits users who need more capacity than Lite; the higher allowance is the key reason to pay the additional monthly cost.

Pro costs $200 a month, billed monthly, and raises usage to 20 times Lite while adding dedicated support. Its price is difficult to justify for light inbox workloads, but the larger allowance and support may suit heavier users who need direct assistance.

Team costs $50 a month per user, billed monthly. It includes pooled usage, shared playbooks and knowledge, centralized billing and team administration, and priority support. The per-user charge makes team size an important cost factor, while pooled usage and shared resources are aimed at teams coordinating their work rather than individuals.

Enterprise has custom pricing and includes dedicated onboarding, custom AI models, SCIM, SSO, role-based access, and custom data-retention policies. Those controls are oriented toward organizations with more specific access and retention needs, rather than buyers seeking a fixed-price entry tier.

Platforms

Serif lists web access, iOS, and desktop downloads for Mac (arm), Mac (x64), and Windows. It connects with Gmail and Outlook. Android is coming soon, so teams that require an Android app should look elsewhere for now.

Who it's for

Serif is aimed at small businesses and operations teams that handle recurring email and document work. It is a particularly good fit when the shared inbox needs both routine automation and a clear handoff for messages requiring judgment. Teams seeking only a lightweight reply-writing aid, or those that need Android support today, have stronger reasons to consider another option.

Pros and cons

• Pro: Its workflows cover routing, paperwork, quotes, and invoice follow-up as well as common questions, making it useful for operational inboxes.
• Pro: Escalation and approval controls let teams retain oversight of uncertain or sensitive conversations.
• Pro: A $100 credit offer with no card requirement lowers the barrier to trying the service.
• Con: Lite starts at $30 a month, and higher usage requires pricier plans, which may be excessive for modest email volumes.
• Con: Team pricing is per user, so the monthly bill grows with the size of the team.
• Con: Android support is not yet available.

Verdict

Choose Serif if your small business or operations team wants an AI-assisted shared inbox that can handle repeatable work while routing uncertain messages back to people. Its broad operational workflows and approval path are the strongest reasons to pick it. Look elsewhere if you need Android now, have low usage that does not justify a paid tier, or want team pricing that does not scale by user.
