Compare AI email assistants: best of 2025

assistant — ai email assistants in 2025: core tasks and metrics

AI email assistants in 2025 must do five core tasks well: draft emails, summarise long email threads, triage the inbox, manage follow-ups, and send multilingual replies. First, drafting matters because teams still spend hours writing and editing messages. Second, summarising long conversations helps users find decisions and action items fast. Third, triage and priority sorting reduce noise and let people focus on high‑value work. Fourth, follow‑up automation closes loops so customers do not wait. Fifth, multilingual replies enable global teams to respond in native languages. Companies facing email overload report clear gains when they adopt these features.

Measure tools by time saved, response lift, summary accuracy, and data controls. For example, a 2025 study found users of AI assistants reported a 40% reduction in time spent managing emails. Enterprise deployments often show a rise in response rates and better satisfaction; Digital Adoption found a roughly 30% increase in email response rates for some teams. Track edit rate on draft emails, the percent of correct follow‑ups created, and a privacy/compliance score for sources the assistant accesses.

Tools like Superhuman, Microsoft Copilot, and Gmail/Gemini each show different strengths. Superhuman focuses on speed and shortcuts, Microsoft Copilot excels at context‑aware drafts across microsoft 365, and Gmail bundles Gemini with native Workspace links for easy collaboration. Lindy notes that the best tools now act as “comprehensive inbox managers” that adapt to your style and preferences. Still, human review stays necessary for sensitive or legal messages and for any full‑fledged email that cites internal systems. For logistics teams that need grounded replies, virtualworkforce.ai offers no‑code connectors so agents draft responses directly from ERP and WMS data, which helps teams manage emails and reduce errors.

When you evaluate an assistant, test it on three email types: support tickets, short status updates, and sales outreach. Time the edits you make. Note how often the tool proposes follow‑ups. Also check how well it handles shared inbox scenarios and whether it preserves the original email context when summarising the entire email thread. These labs give you the data to pick the right ai for your workflows.

inbox management and productivity — how ai for email can automate your email

AI for email shines when it automates repetitive inbox tasks and boosts productivity. Practical features include automatic categorisation, priority sorting, snooze and follow‑up reminders, suggested replies, and rules that run on arrival. Teams with high email volume often enable thread summaries, single‑click replies, and rule‑based routing. These features cut wasted time and reduce context switching. They also lower error rates for replies that require data lookups.

Which features deliver the biggest gains? Start with summarising email threads, then add priority sorting and one‑click replies. Summaries let you triage faster. Priority sorting surfaces the messages that need immediate attention. One‑click replies handle low‑value emails with consistent tone and speed. Together these reduce the time people spend in their inbox and improve response quality. If you want metrics, track minutes per email before and after you enable automations. Many teams see measurable productivity improvements within days.

Actionable checklist: first turn on summaries, next enable suggested replies, then configure follow‑up nudges and rules for common senders. Also set escalation paths so that the assistant flags messages for human review when required. If you manage a shared inbox, confirm that the assistant preserves thread history and can write context‑aware drafts that cite prior messages. For shipping and order teams, virtualworkforce.ai connects to ERP/TMS/WMS so replies reference live order data, which means fewer manual lookups and faster SLA compliance. For those who run email campaigns or frequent support cycles, a pilot that measures time saved and quality of replies will prove ROI quickly.

gmail — email with ai: use an ai inside Gmail (Gemini & Help Me Write)

Gmail in 2025 includes built‑in AI that helps you write and manage messages. Gmail’s Gemini features such as Help Me Write generate drafts, propose tone adjustments, and deliver thread summaries. This tight Workspace integration makes it easy to link Docs, Drive, and Calendar. Use Gmail to test an ai email writer on short updates, sales outreach, and routine support replies. Enable Help Me Write, then compare drafts across three scenarios to gauge quality.

Pros include seamless Workspace links, low friction for users already on Gmail, and cost advantages compared with some standalone apps. Cons can include limited customisation compared to products that target ops teams and less deep data fusion for complex workflows. If your work involves heavy ERP lookups, you may prefer a no‑code virtual assistant that connects directly to backend systems rather than a generic compose ai. Try a free trial of Gmail’s advanced features and then test a specialist tool on the same mailbox to compare outcomes.

How to test: prepare three real messages, then run Help Me Write and an external ai tool on each message. Measure edit time and count the number of follow‑ups predicted. Keep a short prompt bank for consistent tone and length. Use canned prompts to speed consistent output across agents. Also check how the assistant handles multiple email accounts and whether it respects labels and rules. If you need to organize your inbox across teams, evaluate shared inbox support and audit logs.

Tip: if you run email marketing or support at scale, use a mix of native Gmail AI and specialist agents. Gmail handles many common emails well, and specialist systems can link to ERP or inventory data to draft accurate customer replies. For logistics operators, read about automating logistics emails with Google Workspace and virtualworkforce.ai for connectors and templates that save time and reduce errors.

microsoft copilot — inbox features that make microsoft copilot a top ai email assistant

Microsoft Copilot brings strong context to Outlook. It looks across email, calendar, and documents to draft replies that cite attachments and prior notes. Copilot can summarise long email threads and attachments, create tasks from action items, and suggest calendar times. These inbox features make it a solid choice if your organisation uses microsoft 365 heavily.

Copilot’s deep tie to Teams and SharePoint helps you convert an email into a task or a meeting quickly. For example, you can summarise a weekly project thread and auto‑create follow‑up tasks. That reduces meeting overhead and keeps stakeholders aligned. Admin controls and data governance are important for enterprise rollouts, so plan for IT approval and a staged deployment. Copilot offers admin tools and compliance settings, which many companies require.

Best fit: organisations that rely on Office apps, use shared mailboxes, and want thread‑aware summaries that reference attachments. If you want an ai email organizer that also updates tasks, Copilot fits well. Try a pilot on a shared inbox first and measure the false positive rate for suggested actions. This gives a view into accuracy and workload impact. Also test how Copilot handles high email volume and whether it respects role‑based access in shared inbox scenarios.

Deployment note: when you deploy Copilot for operations, include stakeholders from IT, legal, and support. Set guardrails for sensitive messages and ensure Copilot’s outputs pass human review for critical communications. For teams that need deeper ERP or shipment data embedded in replies, a connector‑driven agent like virtualworkforce.ai can combine Copilot‑style drafting with live operational data. That approach helps teams manage emails that require both natural language and accurate data updates.

ai assistant — how to use an ai, score tools and keep productivity high

Start pilots small and measure tightly. First, copy a representative mailbox to a test environment and run live threads through the assistant. Track time to draft, edit rate, and how often the assistant suggested actions that saved follow‑ups. That scoring sheet helps you choose the right AI for your team and guides rollout. Use simple metrics: minutes per email, percent of emails auto‑answered, and customer satisfaction or NPS change.

Practical steps: run the ai on a set of 50 messages, then record the average time to finalise a reply. Note whether the assistant preserved the original email context and whether it proposed follow‑ups. When you score tools, use consistent prompts and the same sample emails. Also set guardrails for tone and privacy. For shared inboxes, require a human in the loop for escalations and legal requests. Teams that want AI to help must balance automation and oversight.

Adoption advice: roll out to a small team first, collect example threads, and update admin settings from feedback. Offer a short free trial or pilot for key users and gather edit metrics. If you need to automate email tasks in logistics, try a no‑code virtual assistant that links to shipment and inventory systems. virtualworkforce.ai provides connectors and behavior controls that let ops teams run the ai without writing prompts or code. This approach reduces manual copying across systems and speeds replies, which improves productivity and reduces errors.

Final takeaway: choose the right ai email assistant for your ecosystem—whether you use gmail and outlook, microsoft 365, or specialist tools. Test on real email types, score consistently, and deploy with clear guardrails. That will keep productivity high and ensure the assistant improves outcomes for both teams and customers.
