Should a small business have an email newsletter?

Yes, once you have at least a few dozen past customers or contacts. Email is the one channel you own; algorithms can't take it away. Send monthly, or twice a month if you have enough to say. Keep it short: one useful piece (a seasonal tip, a project story, an answer to a common question), one piece of news, and one clear call to action. Build the list from customers, inquiries and a simple website signup, always with permission and an easy unsubscribe. Use an affordable tool like Mailchimp, Kit or Substack. Reuse your strongest social posts. McCrawAI can set this up as part of a content system: we plan the topics, and we also produce the newsletter from content you're already making.
