Add your contacts

Open the Contacts tab. Each row is one person. Fill the columns with dark headers; SheetBlast fills the grey ones.

Column	Required?	Example / notes
email	Yes	[email protected]
sequence	Yes	Must match a name in the Sequences tab, e.g. intro
first_name	Recommended	Ann
last_name	Optional	Lee
company	Optional	Acme
from_email	Optional	Which sender to use. Empty = first enabled sender; it’s then locked to that row so all follow-ups come from the same address.
timezone	Optional	e.g. Europe/London, America/New_York. The send window follows the recipient’s time. A misspelt timezone is marked ERROR, never guessed.
custom1, custom2	Optional	Anything you want to merge into the email, e.g. a personal first line

Pasting a list from a CSV or another sheet

1. Paste starting in the first empty row, below existing contacts. Always add new contacts at the bottom.
2. Paste one column at a time under the matching header, or arrange your source columns in the same order first.
3. Fill sequence for every new row: type intro in the first cell and drag the fill handle down.

You can add your own columns (e.g. city, pain_point) and use them as merge tags: {{city}}.

SheetBlast automatically skips invalid emails, duplicates and anyone on the DoNotContact tab, and marks them SUPPRESSED.
