Create a campaign

Go to Campaigns›New campaign.

Give the campaign an internal name. Recipients never see this name, so write it for your future self: something like 2026-09 September newsletter rather than Newsletter. When you have two hundred campaigns in the archive, the date prefix is what makes the list readable.

Pick the list you want to send to. You can send to a whole list or narrow it with a segment, which is a saved set of conditions over your contacts, for example everyone who joined in the last 30 days.

If you pick a segment, check the recipient count the interface shows you before moving on. A segment that resolves to zero contacts is the most common reason a campaign appears to send but nobody receives anything. See Segments for how the conditions work.

Set the sender name and sender address. The sender name is what most inboxes display in bold, so it carries more weight than the subject line for whether someone opens the message. Use a name people recognize, usually your company name, or a person's name at your company if that is how you normally correspond.

Set the reply-to address to a mailbox somebody actually reads. Replies are the cheapest signal you will get about your list, and a reply-to that bounces looks worse than no reply at all.

The sender address must be on a domain you have authenticated with SPF, DKIM and DMARC records. See Deliverability overview.

The subject line is the one field worth rewriting three times. Keep it short enough that it does not truncate on a phone, roughly 40 characters of useful information at the front.

Preview text is the snippet the inbox shows after the subject. If you leave it empty, most mail clients pull the first words of your email body instead, which is often "View this email in your browser". Write something that continues the subject rather than repeating it.

If you want a contact's name or another field in the subject line, use a personalization tag with a fallback. A tag without a fallback renders as an empty gap. See Personalization tags.

Build the email either in the drag and drop editor or by pasting your own HTML. Both routes are covered in The email builder.

Every campaign must contain an unsubscribe link. Do not remove it, and do not hide it in white-on-white text. Making unsubscribing hard converts people who would have quietly left into people who report you as spam, and complaints cost you far more than an unsubscribe does.

Send a test to yourself and, if you can, to one address at a different mail provider. Open both. Check the sender name, the subject line, whether images load, whether personalization tags resolved into real values or left holes, and whether the links go where you meant.

Test sends do not go through your list, so they will not consume a contact's suppression status or trigger automation. They do count against your monthly sending allowance.

Choose a send time, or send immediately. Scheduling is covered in Schedule and send, including how time zones are handled and what happens if you need to pause a send that has already started.
