What is Provider Matching?

Learn how provider matching improves deliverability by sending emails from a
sender that matches your lead's email provider.
Overview
Provider matching is a setting in SalesBlink that tries to send each email from a sender that uses the same email provider as your lead. The goal is to keep emails within the same provider ecosystem, which can improve deliverability and reduce the chance of messages landing in spam.
What Is Provider Matching
When provider matching is enabled, SalesBlink checks your lead's email domain to determine which email provider hosts it. It then looks for a connected sender that uses the same provider and sends the email from that sender.
For example:
- If your lead uses Gmail or Google Workspace, SalesBlink sends the email from one of your connected Google senders.
- If your lead uses Outlook or Microsoft 365, SalesBlink sends the email from one of your connected Outlook senders.
When a matching sender is found, the email is delivered through that provider's infrastructure, which can help with inbox placement.
Why Enable Provider Matching
Provider matching is useful because emails sent between addresses on the same provider often benefit from better trust signals. When a Gmail user receives an email from a Gmail sender, or an Outlook user receives an email from an Outlook sender, the receiving provider is more likely to treat the message as legitimate.
Key benefits include:
- Better deliverability — Matching the sender and recipient provider can improve inbox placement.
- Higher sender reputation — Keeping traffic within the same provider reduces cross-provider spam flags.
- Automatic optimization — Once enabled, SalesBlink handles the matching for you.
Prerequisites
Before you enable provider matching, make sure you have:
- At least one connected Google or Outlook mailbox in your SalesBlink account
- The mailboxes added to the sequence as email senders
You can also connect other providers, such as Zoho or custom SMTP/IMAP senders. However, Google and Outlook are the most commonly matched providers.
How to Enable Provider Matching
- Open the sequence you want to configure.
- Go to the Email Sender & Deliverability tab.
- Check the box for Enable Provider Matching.
- Save your changes.
Once enabled, SalesBlink will automatically match each lead to the most appropriate sender based on their email provider.
How Provider Matching Works
When a sequence runs, SalesBlink checks the lead's email domain to identify the provider. It then compares that provider against the senders you selected for the sequence.
Lead's provider | Sender used |
|---|---|
Google Workspace / Gmail | Connected Google sender |
Microsoft 365 / Outlook | Connected Outlook sender |
Other provider | Google sender is preferred if available; otherwise Outlook |
If multiple senders match the same provider, SalesBlink rotates between them to balance load. Each sender's daily limit, sending window, timezone, and random delays are still respected.
Common Scenarios
Only Google senders are connected
Google leads are sent from your Google senders. Outlook and other-provider leads fall back to your Google senders using normal rotation.
Only Outlook senders are connected
Outlook leads are sent from your Outlook senders. Google and other-provider leads fall back to your Outlook senders using normal rotation.
Both Google and Outlook senders are connected
Google leads use Google senders, Outlook leads use Outlook senders, and leads on other providers are sent through Google by default. If Google is not available, Outlook is used as the fallback.
Other providers are also connected
If you have Zoho or another provider connected, leads on that provider are matched to those senders. Leads on providers you have not connected fall back to Google first, then Outlook.
Important Notes
Note: Provider matching relies on the lead's domain MX records to identify the email provider. Custom domains using Google Workspace or Microsoft 365 are detected correctly.
Note: If no matching sender is available, the lead is not skipped. SalesBlink falls back to the standard sender rotation so the email is still sent.
Note: Provider matching is available on Growth, Business, and higher plans. It is not available on the Starter plan.
Frequently Asked Questions
Do I need both Google and Outlook senders for this to work?
No. You need at least one Google or Outlook sender. Having both gives the best results, but the feature works with either.
What happens if my lead uses a provider I have not connected?
The email is sent using your fallback sender. Google is preferred over Outlook when the provider does not match exactly.
Does provider matching skip leads if no exact match is found?
No. The lead is still emailed using your available senders through normal rotation.
Will this override my sender rotation?
Provider matching runs first. If a match is found, that sender group is used. If not, normal rotation takes over.
