The Email Block List is your do-not-contact list. Anyone on it never receives outreach from your BDR agents. Use it for existing customers, competitors, partners, or anyone who has asked not to be contacted. Go to Settings → Email Block List. The list applies to your account only.

​
Addresses and domains

Each entry is either a full email address or a bare domain: Each entry is labelled as an Address or a Domain in the list. Company pages also flag any company email address that’s blocked, whether directly or because its domain is blocked.

​
Block one entry

  1. Click Block entry
  2. Enter an Email address or domain — Alva works out which it is
  3. Optionally add a Reason, such as “Existing client” or “Asked not to be contacted”
  4. Click Block address

​
Import a list

To block many people at once — for example your customer list or a do-not-contact file:
  1. Click Import list
  2. Paste addresses and domains, one per line, or click Upload CSV/TXT. In a spreadsheet, Alva finds the email column for you
  3. Check the summary of how many addresses and domains were found
  4. Optionally turn on Also block domains from these email addresses
  5. Add a Reason if you like, then click Import
You can import up to 10,000 entries at a time. Entries already on the list are skipped.
Also block domains from these email addresses is off by default. Uploading jane@acme.com blocks only Jane. Turn the option on to block everyone at every company in the file — useful for a customer list, where you don’t want agents emailing anyone at those companies.

​
Removing an entry

Find the entry using the search box, then remove it. Agents can contact that address or domain again straight away.

​
Blocked automatically

You don’t need to add these yourself — Alva blocks them from future outreach on its own:
  • Bounced addresses — any address where an email permanently failed to deliver
  • Remove-me replies — anyone who replies asking to be removed, to unsubscribe, or not to be contacted again
These are handled separately and don’t appear on your Email Block List page.

​
Block list or ignore list?

Alva has two lists that sound alike but do different jobs: The Email Ignore List doesn’t stop outreach, and the Email Block List doesn’t stop analysis. See Understanding email analysis.

​
Ask Alva

Alva can add, remove or check a handful of entries for you:
  • “Block acme.com — they’re an existing client”
  • “Add jane@example.com to the block list”
  • “Is globex.com on our block list?”
  • “Unblock john@initech.com”
For a CSV or a longer list, Alva takes you to Settings → Email Block List and asks you to use Import list.
To pause outreach to a company that said “not now” rather than “never”, ask Alva to put it on hold instead. Outreach to that company pauses and starts again after the time you choose.
