Summary / When to Use This
Make sure you and your customers receive task assignments, reminders, and project updates from OnRamp. This article shows you how to allowlist (whitelist) OnRamp senders in the most common email systems so messages don’t get filtered or quarantined.
Before You Begin
You’ll need an IT admin or someone with email security/admin access (Google Admin Console, Microsoft 365 Defender, or your secure email gateway).
Keep these senders handy:
*@onramp.us(all senders from the domain)notifications@onramp.us(system notifications)
If your organization allowlists by IP, ask Support for OnRamp’s sending IPs: support@onramp.us
Steps to Follow
1) Allowlist OnRamp’s Domain and Sender
Add the following to your allowlist/safe senders:
*@onramp.usnotifications@onramp.us
This ensures all OnRamp notifications land in the inbox.
2) Google Workspace (Gmail)
Sign in to Google Admin Console (admin.google.com).
Go to Apps ➝ Google Workspace ➝ Gmail ➝ Spam, phishing, and malware.
Find Approved senders (or Blocked and allowed senders in some UIs) and click Configure or Edit.
Add
*@onramp.us.Click Save and confirm the settings apply to the correct Organizational Unit.
Optional (Quarantine Review):
Go to Email quarantine and release any OnRamp messages; mark them Not spam.
3) Microsoft 365 (Outlook)
Open Microsoft 365 Defender (security.microsoft.com).
Go to Email & collaboration ➝ Policies & rules ➝ Threat policies ➝ Anti-spam.
Edit your Anti-spam inbound policy (or create a custom one).
Under Allowed senders and domains, add:
*@onramp.usnotifications@onramp.us
Save your changes.
Optional (Connection Filtering/IP Allow):
If your org requires IP allowlisting, add OnRamp’s sending IPs in Connection filter policy ➝ IP Allow list (request IPs from support@onramp.us).
Optional (Quarantine Review):
Check Review ➝ Quarantine to release and Mark as not junk for any OnRamp emails.
Email systems update UI labels periodically. If you don’t see the exact names above, search for Allowed/Approved senders, Safe senders, Allowed domains, or Connection filtering in your admin portal.
4) Other Email Providers (Exchange on-prem, Mimecast, Proofpoint, Barracuda, etc.)
Open your email security admin portal.
Add
*@onramp.usandnotifications@onramp.usto your Allowed/Safe Senders and (if supported) Allowed Domains.If your policy requires IP-based allowlisting, add OnRamp’s sending IPs (request from support@onramp.us).
Review Quarantine/Held Messages and release any OnRamp emails; mark them Safe.
Tips & Troubleshooting
Still missing emails?
Ask IT to confirm that both the domain (
*@onramp.us) and sender (notifications@onramp.us) are allowed in all relevant layers: tenant-wide policies, secure email gateway, and any user-level safe sender lists.
Check for transport rules (Exchange/M365) or policies (Gmail, gateways) that might override allowlists—e.g., DMARC quarantine rules or high-confidence phishing actions.
Verify that the recipient’s mailbox isn’t full, forwarding, or redirecting.
Search message trace/email logs for bounces, rejections, or throttling.
Quarantined or flagged as spam?
Release from quarantine and mark Not spam/Allow. This can improve future handling depending on your provider.
Add the sender to Safe senders at the user mailbox level as an extra safeguard.
Need IPs or header samples?
Contact support@onramp.us. We can provide sending IPs and recent message headers to help your IT team fine-tune filtering (SPF/DKIM/DMARC alignment checks, etc.).
