To connect your SendGrid sending account/domain to E-Warmup, you'll use SMTP with an API key. This is the recommended and most secure way.
A verified sender identity or authenticated domain in your SendGrid account (for best deliverability).
Access to your SendGrid dashboard.
Log into your SendGrid dashboard.
Go to Settings → API Keys in the left sidebar.
Click Create API Key.
Give it a descriptive name (e.g., "E-Warmup SMTP").
Select Full Access or at least Mail Send permissions.
Click Create & View and copy the API key immediately (it won't be shown again). Store it securely.
Use these standard SendGrid SMTP details:
SMTP Host: smtp.sendgrid.net
SMTP Port: 587 (recommended with TLS/STARTTLS) or 465 (SSL)
SMTP Username: apikey (exactly this literal string, not your email)
SMTP Password: The full API key you just created (starts with SG.)
Log into your E-Warmup dashboard.
Go to the connection / add inbox section and select SendGrid (or Custom SMTP if not listed separately).
Enter the SMTP details from Step 2.
Enter the IMAP details of your mailbox. Please note that, IMAP details will be your mail receiving credentials in IMAP format. It can be your regular mailbox credentials (for example, Google Workspace or Webmail)
Connect
DONE !!
