Chat, WhatsApp and voicebots get most of the attention in customer service right now, while email is often treated as a legacy channel. The day-to-day reality in many small and mid-sized service teams looks different: complaints with photos attached, contract questions, invoice corrections and requests from business customers still arrive mostly by email. At the same time, email is the channel with the widest gap between what customers expect and what they actually get. That is rarely down to a lack of effort – it is almost always down to how the work is organised.
Why the inbox becomes a bottleneck
A widely cited benchmark by CRM vendor SuperOffice, which contacted 1,000 companies by email, produced a sobering result: 62 percent did not reply at all, and those that did took around twelve hours on average. The figures are a few years old, but the patterns behind them are still what we see in projects today.
The typical setup is a shared mailbox such as info@ or service@. Everyone has access, nobody is responsible. Emails get opened and are therefore marked as read, even though no one is working on them. Others are answered twice. And because the customer hears nothing, they write again or pick up the phone. Every email left sitting in the inbox generates additional volume that makes the backlog grow further.
Not all response times are the same
Anyone who wants to manage email service needs to separate two values: first response time, meaning when the customer first hears something of substance, and resolution time, meaning when the issue is actually solved. Each can be improved with different tools.
- An acknowledgement with real content: Instead of a generic “We have received your message”, it states a case number, a realistic timeframe and, where relevant, which documents are still missing. This prevents follow-up emails.
- Targets by type of request: A cancellation or a fault report cannot wait 24 hours; a general product question can. A single blanket target for all emails means urgent cases get lost in the crowd.
- Honest maths: Targets should be defined in business hours. Promising “within 24 hours” while emails that arrive at 5 pm on Friday are only seen on Monday means breaking that promise systematically.
From shared inbox to case management
The most important step is organisational: every incoming email becomes a case with a status, an owner and a deadline. When the customer replies or follows up, the message is added to the existing case rather than landing in the inbox as a new, unconnected email.
This pays off directly in customer satisfaction. According to the Zendesk CX Trends Report 2026, based on a survey of more than 11,000 consumers and service professionals worldwide, 74 percent of customers are frustrated when they have to repeat information. An agent who can see the previous conversation, earlier calls and chats when opening an email does not have to ask about things that were settled long ago.
Where AI really helps in the email channel
Email is a channel where AI delivers measurable value early on, because the text is already in written form and customers rarely expect an answer within seconds. Useful applications include:
- Classification and urgency: AI recognises whether a message is a cancellation, a complaint or a standard question, and flags critical cases before they disappear in the pile.
- Summarising long threads: For threads with ten messages and several attachments, a short summary saves a noticeable amount of reading time.
- Draft replies: Based on the knowledge base, AI suggests a reply that agents review, adjust and approve.
- Data capture: Customer numbers, order numbers or contract details are extracted from the text automatically and linked to the case.
For sensitive matters such as complaints or goodwill decisions, a person should have the final say. AI speeds up the path to that decision, but it does not replace judgement.
Clearing the backlog and keeping it under control
An inbox with several hundred open emails cannot be cleared on the side. A few simple rules have proven effective:
- Fixed time slots: Emails are handled in dedicated blocks of time, not between two phone calls. This reduces errors and the cost of switching tasks.
- Oldest first, urgent cases ahead: Within each urgency level, emails are handled in the order they arrived, so nothing is left behind permanently.
- Well-maintained templates: Frequently used replies are kept up to date centrally instead of going stale in personal folders.
- A few clear metrics: The share of emails answered within target, the number of cases older than two working days and the follow-up rate quickly show whether things are improving.
Conclusion
Fast email responses are above all a question of organisation: clear ownership, cases instead of loose messages, realistic targets and AI that supports agents rather than replying unchecked. With myContactCenter by ilogixx, email comes together with telephony, chat and WhatsApp in a single interface, is handled as tickets with status and owner, and is linked to the customer history.
