HubSpot Workflows vs. Sequences: What's the Real Difference?

Fact-checked against HubSpot's current documentation, October 2026.

Quick answers: HubSpot Workflows vs. Sequences

HubSpot Workflows and HubSpot Sequences are both automation tools, but built for different jobs. Workflows run marketing automation at scale, many contacts at once. Sequences run one-to-one sales email outreach, one rep to one contact.

  • Workflow enrollment triggers: up to 250 filters per workflow
  • Sequence bulk enrollment: up to 50 contacts at a time
  • Sequence daily send limit: 500 emails (Professional) or 1,000 emails (Enterprise)
  • Sequence length: up to 10 automated emails per sequence
  • Sequences can now attach to a marketing campaign (Marketing Hub Professional or Enterprise)

I may be talking myself out of a job with this one. Still, I was reading this fantastic article from ZenPilot on the power of automated marketing emails.

For those of you who are unaware, HubSpot has two automation features: Workflows and Sequences. The main difference is that emails sent using Workflows are marketing emails, while Sequences send sales emails.

I know what you're thinking. Molly, what's the difference between a Sales and Marketing email? I don't have time for this nonsense! I have 100K contacts to email and only 40 hours a week to do it!

The biggest difference in emailing prospects is that in HubSpot, Marketing emails include the fun unsubscribe text at the bottom of the message. You know that little link that every salesperson loves at the bottom of their emails that screams FORM EMAIL.

With Sequences, emails are sent out through your email client as though you sat down at your computer and wrote a very thoughtful, very helpful message to the email recipient. Best of all, your email will include your professional footer (if you don't already have one set up in HubSpot).

Below are six other differences in Workflows and Sequences as well as tips based on my own experience creating both.

Enrolling Contacts

Workflows

Enrollment is automatic based on the triggers built into the Workflow. Still, you can also manually enroll contacts from within the Workflow or a list as long as they aren't on a suppression (do not email) list or meet the unenrollment triggers.

Sequences

HubSpot users need to enroll contacts into sequences manually. But before we continue, it is important for me to let you know only HubSpot users with seats in Professional or Enterprise level Sales Hub or Service Hub accounts can use the sequences feature. If you don't have a seat, you won't even see the Sequence option in your HubSpot menu (kind of like me looking for my keys whenever I'm running late).

Enrollment Triggers

Workflows

Triggers can be as complicated as you want, but they have a limit of 250. For this reason, the Workflow editor uses branches to help visualize what it will look like when a contact goes through it. Since Workflows can get very complicated, very quickly, I would recommend working with your HubSpot admin to build one.

Sequences

You can always enroll contacts into sequences one by one, but if you are like me and get bored with this kind of monotony, you want a faster solution. Here's the quickest path:

  1. Create a list of contacts with filters matching your enrollment criteria
  2. Open the list and select the contacts you want to enroll (up to 50 at a time)
  3. Click Enroll in sequence at the top of the table and choose your sequence

Enrollment Limitations

Workflows

No limitations, but you can set unenrollment triggers so you can avoid accidentally enrolling the wrong people in your cool Workflow, or automatically unenroll them once a specific action or change has been taken.

Contacts can also be enrolled in multiple Workflows at a time.

Sequences

Users are limited to enrolling 50 contacts at a time, and to a maximum of 500 sequence emails per day for Professional users (1,000 for Enterprise). That's a rolling 24-hour limit, and it counts every email sent that day, not just brand-new enrollments.

So, suppose you have some time to spare and want to enroll 501 contacts into a sequence and have access to a Professional HubSpot Sales or Service account. In that case, you need to spread out the start date. That isn't to say that you need to wait multiple days to enroll everyone. You will need to limit it so that 500 of your contacts can start the sequence on Monday. The last contact will need to start the sequence on Tuesday.

Contacts can only be in one sequence at a time. If you try to enroll someone who is already in a Sequence, you need to wait until they have completed or been unenrolled from their current sequence before you can enroll them in a new one. This is why I would use an active list for my bulk enrollments and include a sequence enrollment-based filter.

Campaigns

Workflows

You can assign a Workflow to a campaign in its Settings tab. You can even create a new campaign specifically for your drip campaigns to quantify the amount of revenue that can be attributed to your efforts.

Sequences

Sequences can now be assigned to campaigns too. If you have a Marketing Hub Professional or Enterprise subscription, you'll see an “Add to marketing campaign” option right on the sequence.

Length

Workflows

I have not found a limit to the number of steps or actions a workflow has. Nor is there a limit to the number of contacts you can enroll in a Workflow.

On the plus side, this means you can make changes to a large number of records in your HubSpot database at one time (for example, you could assign everyone associated with a company to a specific HubSpot user). However, this also means that if you goof up the enrollment triggers, you can accidentally send thousands of contacts the wrong email.

Worth knowing: a Company-based Workflow with a send email action won't necessarily reach every associated contact, there's a cap on how many it'll actually email. Test with a small list before trusting it at scale.

Sequences

Sequences have a limit of 10 automated emails.

To avoid bombarding your contact with emails, I recommend spacing out your communications by at least 4 business days. Still, sequences are an excellent choice for long-term communication. Your best move is to use them for simple date-specific events like conferences, webinars, limited sales, or new product launches.

Unenrolling Contacts

Workflows

Workflows will continue running until they are turned off. If you turn a workflow off while contacts are enrolled in it, they will continue through the different branches and delays, but they will not receive emails.

You can also manually unenroll a contact from a workflow within the Workflow's enrollment history tab.

Sequences

There are a few ways contacts can end a sequence:

  • They reply to the email (note: HubSpot tries to filter out autoresponders, like out-of-office replies, so those usually won't trigger unenrollment)
  • They book a meeting with you using your HubSpot meeting calendar
  • They complete the sequence
  • You pause or unenroll them
  • They get added to the universal bounce list while in the sequence
  • They click the unsubscribe link in one of the sequence emails

A Friendly Reminder to ALWAYS TEST YOUR AUTOMATIONS!

With sequences, I recommend enrolling yourself first and manually altering the delay dates to ensure you receive each email in a prompt fashion.

With workflows, you can enter names or emails of contacts in your database to ensure the right people meet the enrollment requirements and the wrong people don't. I would also recommend enrolling yourself in the Workflow (just make sure you don't meet the unenrollment triggers).

Whatever you do, be sure that any marketing materials, blog articles, videos, or multimedia cited in your automated emails are published or “live” BEFORE you begin enrolling people in Workflows and Sequences.

It is like a snapshot in time when you enroll someone in a sequence. Your contacts will receive the version of the sequence that existed when you first enrolled them. If you enroll 4 or 400 contacts in a sequence, then notice that one of your email templates has a spelling error and fix the problem, those 4 or 400 contacts will see the janky version of that email in their inbox. Yikes!

Drop a comment and let me know which one you reach for more, Workflows or Sequences.

Now, if you'll excuse me, I need to find my keys…

Frequently Asked Questions
