Newsletter vs cold email: two lists, two jobs keep subscribers and leads apart
A newsletter goes to people who asked for it. A cold email goes to a company you chose. Mixing the two lists causes most of the trouble.
- No credits, no data tax
- Your data stays yours
- Email only, on purpose
- Unlimited users
Different people, different promise
Newsletter vs cold email is not really a choice between two tools. They do different jobs for different lists. A newsletter goes to people who signed up and expect to hear from you regularly. A cold email goes to a company you picked yourself, with one reason to write, and it has to earn a reply on its own.
The trouble starts when the lists get mixed. Prospects end up on a newsletter they never asked for, or subscribers get a sales email that reads like a stranger wrote it. Keep them apart: subscribers in your newsletter tool, companies you chose in a lead database.
The rules also differ. Consent and the right to object work differently for marketing to people who signed up and for a first message to a business, and they differ per country; the UK ICO explains direct marketing rules on its website. We do not promise compliance. What helps is a lead record that keeps the source and date of every company and skips anyone who opted out.
How the two jobs differ
Who is on the list
Newsletter: people who subscribed. Cold email: companies you selected because they fit, with a source you can name.
How often you write
Newsletter: on a fixed rhythm. Cold email: once, with a reason, and again only when there is a new reason.
What you measure
Newsletter: whether people stay subscribed and read. Cold email: replies per segment and which companies moved to Replied.
Which tool fits
A newsletter suite for subscribers. Riftjaw for companies you chose: it is email only, on purpose, and not a newsletter suite.
Keep the two lists apart in three steps
Split the files
Put subscribers in your newsletter tool and companies you selected in a lead database. Do not import one into the other.
Mark where each company came from
Keep the source and date on every lead record at import. See import lists.
Send each list its own message
Write a cold email to one segment with one reason to write, and send it in batches of 10. See campaigns in small batches.
Frequently asked questions
What is the difference between a newsletter and a cold email?
A newsletter goes on a regular rhythm to people who asked for it. A cold email is a single message to a company you chose, with one reason to write. Different list, different promise, different tone.
Can I add prospects to my newsletter?
Not without asking them first. Someone who never signed up did not ask for a newsletter. Write to them as a prospect and offer the newsletter as a link they can choose.
Is Riftjaw a newsletter tool?
No. Riftjaw is email only, on purpose, and not a newsletter suite for large subscriber lists. It sends cold email to segments of companies you chose, in batches of 10.
Do unsubscribes from a cold email carry over?
In Riftjaw, anyone who unsubscribes or objects goes into the opt-out register and is skipped in every later campaign. If you also run a newsletter, remove that address there yourself.
Do I need credits?
No. There are no credits and no cost per record: a flat price per plan, and the size of your list does not change the price.
What is Riftjaw?
Riftjaw is a B2B lead database you own: import the companies you collect, keep every record with its source, sort them into segments and reach them by email in small batches. Each account runs on its own private server with its own database.
