What’s so special about CodeTwo Autoresponders
- Central management for the entire organization: IT admins can build rules that apply to any user, group, department, or shared mailbox, eliminating the need for users to manually configure their own auto replies.
- Works with every mail client and device: Because replies are added server‑side in Azure, it doesn’t matter if emails are sent from Outlook, mobile apps, Apple Mail, third‑party clients, or webmail.
- Smart reply rules and full customization: Rules can target emails based on:
- specific recipients or groups
- messages sent from internal/external users
- keywords or phrases
- time windows (business hours, weekends, holidays)
- inactive, deleted, or shared mailboxes
- Fully branded, HTML‑based autoresponder templates: Build professional auto replies that include:
- HTML layouts
- images & banners
- links & CTAs
- personalized email signatures
- custom From/To/Subject fields
- Advanced scheduling with Limiter & Scheduler: Control how many auto replies a sender receives (e.g., one per day) and schedule recurring or one‑time replies for events, campaigns, staff changes, or maintenance windows.
- Integrated with email signature rules: Autoresponders live inside the CodeTwo Email Signatures 365 ecosystem, letting organizations unify branding, signatures, surveys, and auto replies in one platform.
Advantages of CodeTwo Autoresponders
- Effortless Out‑of‑Office & absence management: Admins can configure OOF replies for employees, entire departments, or service mailboxes especially helpful for HR, Support, or staff on leave.
- Improved customer communication: Autoresponders can notify customers instantly when:
- a message is received
- a case/ticket is created
- someone is unavailable
- the mailbox is no longer monitored
- contact details have changed
- Brand‑consistent auto replies for all departments: Ensure every automated message reflects the corporate identity, with logos, banners, and standardized content.
- Ideal for service teams (Support, Sales, CRM): Automatically send personalized confirmation messages or workflow-triggered communications tailored to the sender or topic.
- Flexible beyond native Exchange limitations: Native auto replies are user‑configured and extremely limited. CodeTwo adds:
- multiple rules
- keyword triggers
- custom sender/recipient
- complex schedules
- multi‑department logic
- No end‑user configuration required: Everything is configured centrally by IT or delegated admins users don’t have to set anything in Outlook.
