Hi, some company contacts are blocked on Hubspot due to “invalid” e-mail adress, event hough it’s valid and connected to Hubspot. I can’t unbounce them due to an error: **Unable to unbounce email** We couldn’t unbounce X. Please try again. Is there a way to fix this? ---

Hello @Dorota, If you’re on the free tools, this is not easy to resolve. Maybe @CommunityTeam can assist? Alternatively, if you upgrade to any paid subscription for a month, you gain access to email support who can check what’s going on directly in your portal. Best regards ---

Hi @Dorota, If the email addresses are valid, it may be worth checking whether all affected contacts belong to the same company domain. Sometimes the issue can be related to domain-level deliverability settings rather than individual email addresses. Hopefully the Community Manager can help identify the exact cause. ---

If the email address is valid but HubSpot still won’t let you unbounce it, I’d first verify that the contact doesn’t have any typos or hidden spaces in the email address. You could also try updating the email, saving the contact, and then changing it back to see if it refreshes the record. If the issue persists and the error is simply “Please try again,” it may be a backend issue rather than a problem with the contact itself. In that case, I’d recommend contacting HubSpot Support with the contact record and a screenshot of the error so they can check the bounce status on their end. ---

HubSpot applies a global hard-bounce block to protect your sender reputation. Once a contact registers a hard bounce, HubSpot automatically excludes them from all future marketing sends. If you have verified that the email is now valid, here is how you resolve this: For Paid Tiers (Starter, Professional, Enterprise): You can manually unbounce the contact directly on their record. Go to the contact’s profile, hover over the “Email” property at the top left, click the warning banner that says “Bounced,” and select “Unbounce.” For Free Tiers: HubSpot does not allow manual unbouncing on free accounts to prevent spam abuse. To resolve this without upgrading, you must have the recipient send a direct, manual email from their inbox to your sending address (the one connected to your HubSpot portal). Once HubSpot’s tracking system registers an incoming, two-way email exchange from that address, it will automatically clear the hard-bounce flag on that contact record. ---

Just to add to what @SamuelOliver said, a valid email can still bounce for a few reasons that have nothing to do with the address being wrong: - the mailbox was full at that moment - a firewall or security filter on the recipient’s side blocked it - your sending domain needs to be allowlist before it can reach them So the steps mentioned above really do help here. Going forward, I would suggest adding a real time email validation app into your workflow. [HubSpot’s marketplace](https://ecosystem.hubspot.com/marketplace/explore/products?eco_search=EMAIL+validation+) has several that integrate directly with your CRM and can catch this kind of problem upfront, before you send,
