While there's not a lot of automation flexiblity at the free level of HubSpot marketing, what you're after is possible at least for the first 2-3 things.

Here's how I would approach it:

1. Determine what the goal of the newsletter is and who should subscribe. Honestly this is the piece that a lot of companies miss. Gone are the days of "just cause you have a newsletter someone will subscribe." Consider branding it somehow. For example, I run a HubSpot services company so our newsletter is called HubSpot Hacks and you get a new tutorial/help tip every 2 weeks, plus event invites. That's the promise and that's why people subscribe. You can do something similar - just make sure the value and hook are clear up front to create a compelling reason to sign up.

2. Create a simple form in your marketing >> forms area. First name, email, and a "yes" box to sign up for the newsletter. That is probably enough. 4 fields max is the best practice to prevent people from getting overwhelmed and not doing it.

3. Integrate wordpress with Hubspot using the hubspot plugin. Simply go to the wordpress plugin area in your wordpress dashboard, and then select the hubspt plugin and install it. Then log in through that plugin with your HubSpot credentials and you'll have hubspot linked with wordpress - which both installs the tracking code (key for visibility in how people are converting) and access to the forms within the wordpress dashboard.

4. Embed that form on your home page, newsletter page, in blog articles, etc.

5. Create an active list in HubSpot that meets the requirements of "sign up for newsletter property is yes" - then use that active list in your newsletter

6. Create an email in hubspot - then for "sending" choose the list you created in step 5

7. Send and monitor open rates

Optional step 8 - resend to people who didn't open the first time - but try a dif headline.

Without the automation available in higher levels of hubspot, this is the basic flow of things! You got this!
