Email System

Email System

Add sending domains, verify DNS, create email addresses, and warm up mailboxes for better deliverability.


What is Email System?

Email System is where you set up email sending (and optionally receiving) for your brand — separate from Email Outreach campaigns. Open it at app.swai.ai/setting/email-system.

You use it to:

Main screens

Screen What it’s for
Settings → Email System → Domains (open) Sending domain verification
Settings → Email System → Email addresses (open) Addresses like hello@yourdomain.com, warmup, and mail-app passwords

Tabs: Domains, Email addresses.

Warning: Do not confuse this with Settings → Domains (open) (funnels, websites, stores, blogs). See Domains for those.

Tip: For mass email and outreach, it is usually better to send from a different domain than your main website domain. That protects the reputation of the brand name customers visit on the web. See Domains and email marketing. If you buy through SWAI, you can add an optional email / campaign domain in the same Buy flow.


Before you start

  1. Own a domain where you can edit DNS.
  2. Plan usernames (hello, support, sales) after the domain is verified.
  3. Allow up to 48 hours for DNS to update.
  4. For warmup, keep enough credits (see Warmup).

Tip: Verify at least one domain before creating email addresses — Add email address stays unavailable until then.


Quick start

  1. Open Settings → Email System → Domains → Add domain (or go to app.swai.ai/setting/email-system).
  2. Enter the domain → Add domain.
  3. In DNS configuration, use Set up DNS with {provider} when offered, or copy the records manually → Got it.
  4. Click Check status until status is verified.
  5. Open Email addresses → Add email address → set Username and Domain → Create email address.
  6. (Recommended for new domains) Turn on Warmup for that address and wait until the badge shows Warming or Healthy before large campaigns.

Domains tab

Section: Sending domains — Add and verify domains used for outbound email.

Control Label
Button Add domain
Columns Domain, Status, Receiving, Added, Actions
Search Search domains…
Empty No domains yet. Add one to start sending email.

Status and receiving

You may see Meaning
Status For example pending or verified
Receiving enabled Ready to receive email
Receiving disabled Receiving not ready — tip: MX records are not configured. View DNS details to add the required MX records for this domain.

Add domain

Modal Add domain — Enter the domain you want to use for sending emails. → Add domain.

Field Notes
Domain name For example mail.company.com

Helper: Supports root domains and subdomains such as mail.company.com or postmailing.example.com.

DNS configuration

Actions: Check status, View DNS, Delete.

Modal DNS configuration.

When your domain provider supports it, SWAI offers Set up DNS with {provider}. That applies the verification records for this domain. Optionally enable Also add MX records for receiving. You confirm on the provider site, return to Email System, then use Check status.

Otherwise (or via Set up manually instead):

Subtitle: Add these records at your DNS provider to verify the domain and enable receiving. → Got it.

Section What to do
Intro Copy each record below into your DNS provider. Propagation can take up to 48 hours.
Verification records Follow the CNAME and TXT records shown (unique per domain)
MX records for receiving Add the MX records shown if you want receiving

Alert After adding records: Use "Check status" in the domains list to refresh verification once DNS has propagated.

Delete domain

Delete domain — Are you sure you want to delete this domain? This action cannot be undone. → Delete / Cancel.


Email addresses tab

Section: Email addresses — Create addresses under your verified sending domains. Warmup costs 90 credits per mailbox each month. Use the key icon for IMAP/SMTP mail-app passwords.

Control Label
Button Add email address (unavailable without verified domains)
Alert No verified domains — Verify at least one domain in the Domains tab before creating email addresses.
Columns Email address, Domain, Status, Warmup, Created, Actions
Search Search email addresses…
Empty No email addresses yet. Create one under a verified domain.

Add email address

Modal Add email address — Choose a verified domain and set the username for the new address. → Create email address.

Field Notes
Username Part before @ (for example hello)
Domain Select a domain — verified only
Preview Shows username@domain

Alert Verified domain required: Email addresses can only be created under verified domains. Complete DNS verification first if your domain is still pending.

If incomplete: Alert / Please select a domain and enter a username.

IMAP / SMTP password (mail apps)

Use the key icon on a row to issue an IMAP/SMTP password for Gmail, Outlook, Apple Mail, or similar.

Modal IMAP / SMTP access — Copy these settings into Gmail, Outlook, or Apple Mail. The password is shown once.

Setting Typical value
Username Full email address
Password Shown once when issued
IMAP host imap.mail.swai.ai (port 993, SSL/TLS)
SMTP host smtp.mail.swai.ai (port 587, STARTTLS)

Warning: Save the password immediately. Issuing again replaces it. Warmup uses a separate password and is not affected when you re-issue the mail-app password.

Delete email address

Delete email address — Are you sure you want to delete this email address? This action cannot be undone. → Delete / Cancel.

Deleting an address also turns off warmup for that mailbox (if it was enabled).


Email warmup

Warmup gradually builds sender reputation for a SWAI mailbox by exchanging realistic mail with a trusted network. Use it for new domains and addresses before high-volume Email Outreach or agent sends.

Warmup is not the same as Progressive Drip / Drip Sending Mode in Email Outreach (that only ramps campaign volume). Warmup builds engagement signals with inbox providers. See Email Outreach.

Cost

Tip: You need enough credits before enabling. If balance is too low, enable fails with a message about the 90-credit cost.

How to turn warmup on

  1. Open Settings → Email System → Email addresses.
  2. Find the address → in the Warmup column, turn the switch on.
  3. Wait for the badge to leave Connecting and show Warming (or Healthy later).
  4. Keep DNS (SPF/DKIM/DMARC as required) correct — warmup cannot fix a misconfigured domain.

Warmup does not start automatically when you create an address. Opt in per mailbox.

Warmup status badges

Badge Meaning
Off Warmup is not running
Connecting SWAI is connecting the mailbox to the warmup network
Warming Warmup is active; reputation is still building
Healthy Recent warmup health looks strong (often includes a score %)
Paused Warmup paused (for example billing)
Error Connection or provider problem — turn off and on again, or contact support

Refresh the page if the badge looks stuck. Status also updates in the background (about every 20 minutes).

How long to wait

What warmup does not do


Common warnings and troubleshooting

Domain stuck on pending

  1. Re-open View DNS and compare every name and value.
  2. Wait for DNS to update (up to 48 hours).
  3. Click Check status again.
  4. Confirm you edited DNS for the correct domain at your provider.

Automatic DNS setup isn’t offered

Not every domain provider supports one-click DNS setup. When it isn’t available, copy the verification and MX records shown in DNS configuration. The screen explains the reason when SWAI can detect it.

Receiving disabled

Add the MX records from DNS configuration. Sending can work when verified even if receiving is still disabled.

Can’t add an email address

Verify a domain first. Select a verified domain and a non-empty username.

Warmup stays Off or shows Error

  1. Confirm the domain is verified and the address is Active.
  2. Check you have at least 90 credits.
  3. Toggle warmup off, wait a moment, then on again.
  4. Confirm receiving/MX is set if the warmup network must deliver replies.
  5. Contact support with the email address and any error text if it still fails.

Warmup badge stuck on Connecting

Refresh the page after a minute. If it never changes, treat it like Error above and contact support.

Wrong page for my website domain

Use Domains for funnels and websites. Use Email System only for mail setup.

Should I send campaigns from my website domain?

Usually no for high-volume outreach. Prefer a separate sending domain so complaints and spam signals do not damage the name on your public site. See Domains and email marketing.
