    The problem

    Email is the channel everyone underestimates

    Most modern support tools treat email like a fading channel — but for B2B SaaS, banking, healthcare and any business with invoices, email is still where 40-70% of post-purchase conversations live. The problem is that "support@" or "billing@" are usually shared Gmail or Outlook accounts where five people log in simultaneously, accidentally archive each other's threads, send replies from the wrong signature, and miss SLAs because nobody knows whose turn it is. The CC and BCC spaghetti gets worse the moment a customer loops in their finance team or their legal counsel.

    Classic helpdesks like Zendesk and Freshdesk solve this, but at the cost of fragmenting your conversation graph. The same customer who emails support@ also DMs you on Instagram and chats on the website — and in a Zendesk world, those are three separate tickets with three separate IDs, none of which know about each other.

    Wachat's email inbox is built so that an email from raj@example.com lands next to his WhatsApp thread, his Instagram DMs and his web chats. One contact, one history, one assignee. The email itself keeps every header, attachment, threading ID and inline image — Gmail or Outlook continues to work as the underlying transport, but your team works inside the Wachat shared inbox.

    What it is

    Email Inbox, in depth.

    Wachat connects to Gmail via Google Workspace OAuth and to Microsoft 365 via Microsoft Graph OAuth, both with the minimum permissions required to read inbox, send mail, and apply labels. Connection takes under 90 seconds and supports both individual addresses (raj@yourdomain.com) and group addresses (support@yourdomain.com). The original mailbox remains the source of truth — every email you send through Wachat lands in the Gmail/Outlook Sent folder with the right headers, so it shows up correctly even when the customer replies from their phone's native mail client.

    Threading is built on RFC 2822 Message-ID and In-Reply-To headers rather than subject-line matching, which means conversations stay correctly grouped even when a customer changes the subject or starts a new email referencing the old one. Attachments up to 25 MB (Gmail) or 35 MB (Microsoft) are streamed inline; larger files are auto-uploaded to SabNode's storage with a signed download link. HTML formatting, inline images and forwarded attachments are preserved exactly as the customer sent them.

    Per-team and per-address signatures handle the operational reality: your sales team signs "Priya, Inside Sales" with calendar booking link, while your support team signs "Wachat Support" with help-centre link. Reply-to addresses route correctly — a customer who emails support@ gets a reply from support@, even if the actual agent is replying from her personal account. Out-of-office, vacation responders and per-domain auto-archivers are configurable inside Wachat without touching Gmail or Outlook settings.

    Bidirectional sync means Gmail labels and Outlook folders are mirrored as Wachat labels, and label changes flow both ways. Mark a thread "Resolved" in Wachat and it gets the matching Gmail label; archive it in Gmail and it disappears from the Wachat queue. Existing Gmail filters keep working, so the routing rules your team has built up over years are not thrown away.

    Capabilities

    Everything you get with Email Inbox.

    7 capabilities
    01

    OAuth Gmail and Outlook

    Connect Google Workspace mailboxes via OAuth 2.0 with offline scope, or Microsoft 365 via Microsoft Graph. No IMAP credentials, no app passwords. Re-auth happens silently on token refresh; admins see a connection-health indicator per address.

    02

    RFC-grade threading

    Threading uses Message-ID and In-Reply-To headers, not subject matching. Forwarded emails, replies from mobile mail clients and subject-line changes all collapse correctly into one conversation, preserving the full audit trail.

    03

    Per-team signatures

    Configure signatures per team, per address or per agent with rich HTML — logo, calendar link, help-centre URL, legal disclaimer. Wachat picks the right one automatically based on the team handling the conversation and the reply-to address.

    04

    Attachment handling up to 35 MB

    Inline attachments up to 25 MB (Gmail) or 35 MB (Microsoft) ride the native mail transport. Larger files are uploaded to SabFiles, replaced with a signed download link that expires after 30 days, and tracked for who opened the file.

    05

    Bidirectional label sync

    Gmail labels and Outlook folders mirror as Wachat labels. Apply, remove or rename in either system and changes propagate within 60 seconds. Existing Gmail filter rules keep firing — Wachat does not break what you have already built.

    06

    CC, BCC and forward handling

    CC and BCC are visible in the inbox composer with autocomplete from the CRM. Forwarded threads preserve the full quoted history but render only the new content above the fold, so agents see what matters first.

    07

    SPF, DKIM and DMARC validation

    Outbound mail uses your domain via DKIM signing, so deliverability matches your existing setup. Inbound mail is parsed for SPF/DKIM/DMARC results and flagged when failures suggest phishing — useful for finance and HR inboxes.

    Use cases

    Built for the way teams actually work.

    SaaSCase 01

    B2B SaaS billing queries

    A vertical SaaS routes billing@ emails to a finance team queue with a 4-hour SLA. CC'd AEs see the thread in their inbox but cannot reply. Invoice attachments are auto-attached to the customer's CRM record, and refund requests trigger a Razorpay refund flow with one click — no swivel-chair to Stripe.

    HealthcareCase 02

    Healthcare report delivery

    A diagnostics lab sends test reports as encrypted PDF attachments from reports@. Wachat threads the patient's "where is my report" follow-up email into the same conversation as the original booking on WhatsApp, so the same agent sees full context — no medical history shared across threads.

    StaffingCase 03

    Recruitment candidate pipeline

    An IT staffing firm uses careers@ as a real inbox. Resumes attached to inbound emails are auto-uploaded to SabFiles, parsed for skills, and a candidate record is created in the CRM. Recruiters reply from a per-role signature ("Sneha, Senior Recruiter, Java Practice") with a Calendly link.

    E-commerceCase 04

    E-commerce post-purchase support

    A premium furniture retailer threads inbound emails with the order ID into the WhatsApp conversation that originally placed the order. The agent sees the email, the chat, the order line items and the courier ETA in one view, cutting handle time on delivery escalations from 11 minutes to 3.

    Financial ServicesCase 05

    Finance KYC document collection

    A lending startup uses kyc@ to collect PAN, Aadhaar and bank statements. Wachat auto-detects MIME types, redacts attachments for non-KYC team members, and flags anything that fails OCR validation. The KYC officer signs off inside the email thread, and the CRM status flips automatically.

    How it works

    From signup to first send in minutes.

    Email Inbox is included on every SabNode workspace. No separate billing, no extra setup, flip it on from your workspace settings.

    1. 01

      Authorise mailbox

      Click "Connect Gmail" or "Connect Outlook", complete the OAuth consent screen, and the mailbox starts syncing within 30 seconds. Historical sync (last 90 days by default) runs in the background.

    2. 02

      Configure signatures

      Set per-team or per-address signatures using the rich-HTML editor. Drop in your logo, calendar link, support URL and legal disclaimer. Preview against light and dark themes before saving.

    3. 03

      Map labels and routing

      Mirror Gmail labels or Outlook folders as Wachat labels. Build routing rules — for example, emails to billing@ with the word "refund" go to a finance senior with a 2-hour SLA.

    4. 04

      Set SLAs and auto-responders

      Define first-response SLAs per address and per label. Configure out-of-office, vacation responders and weekend auto-replies. Wachat respects business hours and holiday calendars per team.

    5. 05

      Train the AI replies

      Feed Wachat's AI layer your last 5,000 resolved threads. It learns your tone, common answers and escalation patterns, then suggests replies inline for the agent to accept, edit or discard.

    Frequently asked

    Questions about Email Inbox.

    Can't find what you're looking for? Talk to our team.

    Will my existing Gmail filters keep working?
    Yes. Wachat does not replace Gmail's server-side rules — it sits alongside them. Your existing filters continue to apply labels, archive automatically and forward as configured. Wachat picks up emails as they land in the relevant labels, and any label change Wachat makes is mirrored back to Gmail in under 60 seconds.
    Can I keep using Gmail or Outlook directly for some emails?
    Absolutely. Wachat is additive. Agents who prefer the native client can still respond from Gmail or Outlook — Wachat sees the sent reply via the Sent folder and updates the conversation. Many teams use the native client for personal email and Wachat for shared inboxes like support@ or sales@.
    What happens if the OAuth token expires?
    Wachat refreshes tokens silently using the offline scope granted at connection time. If the user revokes access or changes their password, Wachat shows a clear "reconnect" prompt in the inbox with the affected mailbox highlighted, and queues outbound emails for up to 24 hours so nothing is lost during the brief interruption.
    Does this support custom domains and aliases?
    Yes. Wachat supports any domain configured in Google Workspace or Microsoft 365 — including aliases like sales@, billing@ and brand-specific addresses (support@brandA.com, support@brandB.com). Each alias can route to a different team, carry a different signature, and inherit a different SLA.
    How do attachments larger than 25 MB get handled?
    Wachat detects attachments exceeding the native mail transport limit, uploads them to SabFiles, replaces the attachment with a signed download link valid for 30 days, and notes in the email body that the original file is hosted securely. The recipient clicks the link to download — no quota issues, no bounced emails for being too large.
    Is the historical sync configurable?
    Yes. By default Wachat syncs the last 90 days of email on first connect, which covers most active conversations. Admins can extend to 180 days, 365 days or full history, with the trade-off that initial sync takes longer for very large mailboxes (a 100K-thread mailbox takes about 4 hours to backfill). New mail syncs in near real time via Gmail Push and Microsoft Graph subscriptions.
    Can I migrate from Zendesk, Freshdesk or Help Scout?
    Yes. Wachat provides a one-time importer that ingests CSV exports from Zendesk, Freshdesk and Help Scout, mapping tickets to conversations, agents to users and tags to labels. The migration runs in a sandbox first so you can validate mapping before cutover. Most teams complete a full migration in a weekend with no downtime on the live inbox.
