You can add readers one at a time, but most writers start by importing a list they already have. If you're moving from another email platform, see Switching to AuthorSend first — we can bring your whole account across for you, tags and sequences included.
Import from a CSV
- Go to Subscribers and choose Import.
- Upload a
.csvfile. The first row should be your column headers (name, email, and any custom data you keep). - Map your columns to AuthorSend fields. Obvious matches like Email and First name are matched for you; anything unusual becomes a custom field you can map yourself.
- Optionally assign the whole import to a list or tag so you can find these readers again.
- Review the summary and start the import.
When a reader already exists
If an incoming row matches someone already in your account, you decide the rule before the import runs:
- Skip — keep the existing record untouched.
- Overwrite — replace existing fields with the incoming data.
- Merge — combine the two records field by field.
A reader is never counted twice, no matter how many lists or segments they end up in.
Only import people who asked to hear from you
Importing a list you bought, scraped, or haven't emailed in years is the fastest way to land in spam folders and hurt delivery for everyone. Import readers who opted in — see Improve your deliverability and Stay compliant with CAN-SPAM and GDPR.
