Integrations
Outreach2day is mailboxes, warm-up and a sequencer in one product: import a lead list and send from the campaigns built in. Teams that keep their current sequencer export the mailboxes to it instead. Each page lists the exact fields, settings and fixes for one tool.
Import a lead list into an Outreach2day campaign
Export the list from your data tool, clean it and send it from Outreach2day: campaigns, mailboxes and warm-up in one place.
Keep your sequencer: one-click export
Paste the sequencer's API key once. Mailboxes are added as SMTP/IMAP accounts, new ones follow automatically and disconnected ones are reconnected.
Keep your sequencer: CSV import
Download a CSV of your mailboxes in the tool's import format and upload it there. Each page says which columns match the tool's own template and what to change.
Any other tool that takes SMTP/IMAP
Every Outreach2day mailbox connects with the same settings. The plain Download CSV in the app has them for every mailbox, and the API lists them too.
| SMTP host | outreachmailstream.com |
|---|---|
| SMTP port | 465 (SSL/TLS) |
| IMAP host | outreachmailstream.com |
| IMAP port | 993 (SSL/TLS) |
| Username (SMTP and IMAP) | The full email address |
| Password (SMTP and IMAP) | The mailbox password from the export (the same for SMTP and IMAP) |
