Use this when a customer wants a confirmation, OTP, or notification email sent immediately, not a marketing campaign (that's Auto Responder Integration). Settings & Integration page with API Integration selected, Email API selected in the sub-list, and its profile table (empty) with a New button highlighted **Email Integration** connects ChatSyncs to an email provider so it can send an email **immediately**, the moment something happens in a conversation — an order placed, an appointment booked, an OTP requested. Nothing is stored for later; the email goes out right away. ## How it works They place an order, book an appointment, ask for an OTP, or submit a contact form. That action tells ChatSyncs an email needs to go out. Using whichever profile you connected — SMTP, Mailgun, SES, etc. No delay, no separate marketing tool involved. ``` Customer places an order ↓ ChatSyncs ↓ SMTP / Mailgun / SES ↓ Order Confirmation Email ``` ## Set up a provider Click **New** to add a profile: Email Profile modal with Profile Name, Host, Username, Password, Port, Encryption fields and a provider list: SMTP, Mailgun, Postmark, SES, Mandrill Supported providers: **SMTP** (any generic SMTP server — Host, Username, Password, Port, Encryption), **Mailgun**, **Postmark**, **SES** (Amazon), and **Mandrill**. You can add more than one profile and use a different one per purpose: | Profile | Purpose | | ---------- | ---------------------- | | SMTP | Order confirmations | | Mailgun | Marketing campaigns | | Amazon SES | Internal notifications | ## Real examples **Order confirmation** — a customer orders a laptop through the bot, and ChatSyncs immediately sends: ``` Subject: Order Confirmation Hello Rahul, Thank you for your order. Your order has been successfully placed. Order ID: #12345 ``` **Appointment booking** — the bot confirms a booking, and ChatSyncs sends: ``` Subject: Appointment Confirmed Your appointment is booked. Date: Monday Time: 4:00 PM ``` **OTP verification** — the customer asks for a one-time code, and ChatSyncs sends: ``` Subject: Your OTP Your verification code is: 845921 ``` **Notify your team** — instead of emailing the customer, send the email to your own team when a lead comes in, e.g. after a contact form is filled out: ``` New Lead Received Name: Rahul Phone: +91XXXXXXXXXX Message: I need more information. ``` ## Email Integration vs Auto Responder Integration It's easy to mix these two up because both send email — the difference is *when* and *why*: | | Email Integration | [Auto Responder Integration](/learn/control-panel-auto-responder-integration) | | ------------------- | -------------------------------------------- | ----------------------------------------------------------------------------- | | Sends | Immediately, one email at a time | Later, through a marketing platform | | Used for | OTPs, confirmations, invoices, notifications | Newsletters, offers, follow-up campaigns | | Who sends the email | ChatSyncs, directly | Mailchimp, Brevo, etc. | | Providers | SMTP, Mailgun, Postmark, SES, Mandrill | Mailchimp, Brevo, ActiveCampaign, Mautic, MailWizz | If you want to **build an email list and send marketing campaigns later**, use [Auto Responder Integration](/learn/control-panel-auto-responder-integration) instead. ## Frequently asked Yes — connect an email provider under **Email Integration**, then reference that profile from a bot flow or automation step that sends email. **SMTP**, **Mailgun**, **Postmark**, **SES**, and **Mandrill**. Yes — add multiple profiles (e.g. one SMTP profile, one Mailgun profile) and choose the right one per flow or automation. Email Integration sends a single email right away (an OTP, a confirmation). Auto Responder Integration instead sends the customer's email address to a marketing platform like Mailchimp, which handles newsletters and campaigns on its own schedule — see the comparison table above. If you're using an **SMTP** provider, double-check the **Host**, **Port**, **Username**, **Password**, and **Encryption** settings — a mismatched port or encryption setting is the most common reason a profile saves successfully but emails silently fail to send.
