A sender is the identity your emails come from. Today that’s a mailbox; more channels are coming. Before you can send anything, you need at least one connected mailbox. You can connect as many as you like — every plan includes unlimited mailboxes. Go to Senders and press Add sender (it’s also on the empty-state hero when you have none yet).

​
Choose what to connect

The wizard opens with Add a sender. Pick Cold email (SMS and calls are coming soon). Then choose how to connect:

Google / Gmail

Connect a Gmail or Google Workspace mailbox — either with one-click Google sign-in or a guided app-password setup.

Microsoft

Connect Outlook or Microsoft 365 with one-click sign-in — no app password needed.

Another provider

Zoho, Yahoo, iCloud, Fastmail, Hostinger, Amazon SES, SendGrid, and more, over SMTP.
Whichever method you pick, Norbelys sends one test email to confirm the mailbox can send before it saves it. If the test fails, you’ll see the error right away instead of discovering it mid-campaign.

​
Connect Gmail with an app password

This is the most common Gmail path. Google requires an app password — a special 16-character password just for Norbelys, separate from your normal login. The wizard walks you through it with direct links:
1

Turn on 2-Step Verification

App passwords only exist once 2-Step Verification is on for your Google account. The wizard links straight to the setting.
2

Create an app password

Create one and name it “Norbelys” so you can recognize it later. Google shows you a 16-character code.
3

Paste it in

Enter your name, your Gmail address, and the app password. Norbelys fills in every server setting for you and validates that the password looks right (16 characters, spaces are stripped automatically).
4

Connect

Press Connect Gmail. The button shows “Connecting & sending a test…” while it confirms the mailbox works, then saves it.
If your organization uses Google Workspace, an admin may need to allow the connection. The wizard shows a copyable Client ID and a link to the Admin Console for the one-click Google sign-in path.

​
Connect Microsoft

Choose Connect with Microsoft and you’ll be taken to Microsoft’s secure sign-in (OAuth) for Outlook or Microsoft 365. Approve access and you land back in Norbelys connected — no app password required.

​
Connect another provider over SMTP

Choose Connect another provider to open the SMTP dialog. This works for almost any mailbox.
1

Pick your provider

Select a preset tile (Gmail, iCloud, Microsoft, Yahoo, Zoho, Amazon SES, SendGrid, and more). Picking one auto-fills the SMTP and IMAP server settings and shows a provider-specific note.
2

Set your identity

Enter your From name, From email, and an optional Reply-to address.
3

Enter your SMTP details

For known providers the server fields are filled in for you. Otherwise enter the host, port, security (None / SSL·TLS on 465 / STARTTLS on 587), username (defaults to your From email), and password.
4

Set sending limits

Choose a daily limit (default 30, not counting warmup) and a minimum time gap between emails (default 5 minutes; the cold floor is 3). You can also add a client label and a signature.
5

Add IMAP so replies come back

IMAP is required — enter the IMAP host, port (usually 993), and security. This lets Norbelys read the mailbox so replies stop sequences automatically and land in your inbox.
6

Connect

Press Connect mailbox. Norbelys sends a quick test to confirm the mailbox can send before connecting it.
Some providers like Amazon SES and SendGrid are SMTP relays, not inboxes — they can send but can’t receive replies. If you use one, you’ll still need an IMAP inbox somewhere so replies and warmup can work.

​
An optional BCC to your CRM

In the SMTP dialog you can add a BCC to CRM address. Every email the mailbox sends is silently blind-copied there, which is handy for logging outreach in an external CRM.

​
What happens after connecting

Once a mailbox is connected it appears in your Senders list. A new mailbox should warm up before running cold campaigns. From here you can manage its health, pacing, and state — see Managing senders.
