GetReplies sends campaign emails through your own mailboxes — not through a shared sending service. This means your domain reputation is entirely yours, and your emails come from an address your prospects can recognise and reply to.
Important — use a secondary domain for outreach
Do not use your primary business domain (the one you use for proposals, invoices, and day-to-day email) for cold outreach campaigns.
Why: Cold outreach can produce bounces when prospects change jobs or email IDs expire. High bounce rates can damage your primary domain's sending reputation — and push your transactional email into spam.
Best practice: Register a closely related domain (e.g. if your primary is getco.com, register getco.io or getcos.com) and use that for outreach. Forward it back to your main website so it looks legitimate to prospects.
Supported providers
GetReplies connects to any email provider that supports SMTP and IMAP:
Gmail and Google Workspace via native integration
Microsoft 365 and Outlook via native integration
Custom mailboxes — Zoho Mail, Hostinger, Namecheap, GoDaddy, and others via SMTP/IMAP
How to add a mailbox
Go to Accounts in the left navigation.
Click Add account → Email.
Choose your provider: Google / Gmail, Microsoft, or Custom.
For Gmail: Connect using an App Password.
For Microsoft: Connect with Microsoft OAuth.
For custom providers: Enter your SMTP host, port, IMAP host, port, email address, and App Password.
GetReplies will run a set of checks on your mailbox configuration and show you the results (see below).
Set your sender name and configure your daily limits.
Save. Your mailbox is now connected and warmup will begin automatically.
Mailbox health checks
When you connect a mailbox, GetReplies runs the following checks and shows a pass or warning result for each:
✓ Passed | SPF record — verifies your domain is authorised to send email |
✓ Passed | DKIM record — verifies emails are cryptographically signed by your domain |
✓ Passed | DMARC record — tells receiving servers what to do with unauthenticated email |
✓ Passed | Domain forwarding — secondary domain redirects to your main website |
✓ Passed | Send test — confirms the mailbox can send email |
✓ Passed | Receive test — confirms the mailbox can receive email |
While GetReplies allows you to send emails even if DKIM, DMARC and Domain forwarding are not set, there is a high chance that your mails will land in spam. Hence, it is recommnded to complete all these settings.
Troubleshooting — DKIM showing as failed even after setup
This is usually caused by an incorrect App Password, not the DKIM DNS record itself. GetReplies checks DKIM by sending a test email and reading the signature in the received message — so if the mailbox can't send, DKIM will also show as failed.
Fix: Go to your Google account → Security → App Passwords. Delete the existing GetReplies password and create a fresh one. When entering it into GetReplies, remove any spaces. Then reconnect the mailbox.
Daily sending limits
GetReplies lets you set a daily campaign limit per mailbox — the maximum number of campaign emails it will send in a day. You also control whether the platform ramps up your volume automatically for newer mailboxes.
| ⚙ Accounts → Mailbox settings — recommended defaults |
Daily campaign limit | 20–25 emails/day (including follow-ups) |
Continuous warmup | ON — always leave this running |
Ramp-up | ON for mailboxes less than 3 months old |
Daily campaign limit | If Ramp-up is ON, then the platform sets this limit. Otherwise, set it between 25–30 emails/day (including follow-ups) depending on age of the mailbox |
Sender name | Your first and last name |
Time zone | Match the country your mailbox operates in |
If you want to reach a higher daily volume, add more mailboxes rather than raising individual limits. Three mailboxes at 25–30 emails/day is safer and more effective than one mailbox at 75-90 emails/day.
Why 25–30 and not more?
Google and Microsoft actively monitor sending patterns. Mailboxes that suddenly send large volumes — especially to addresses that bounce — get flagged and can be suspended.
25–30 per day per mailbox is the ceiling that our team has tested extensively across hundreds of customers without triggering issues. The Starter plan includes 5 mailboxes, giving you 100–125 emails/day total.
Adding more mailboxes
You can add multiple mailboxes to a single campaign. GetReplies automatically rotates between them — it assigns each contact to a mailbox and sends all messages to that contact from the same mailbox throughout the sequence.
• Starter plan: up to 5 mailboxes
• Professional plan: up to 10 mailboxes
If you need to scale beyond your plan's mailbox limit, contact us to discuss custom options.
