HubSpot’s email marketing tools cover campaign creation, automation, A/B testing, and deliverability management. For most B2B marketing teams, HubSpot email is solid enough to replace a standalone email tool – but it has specific limits on design flexibility and deliverability configuration that larger senders need to understand. This guide covers how to use HubSpot email effectively, what the deliverability considerations are, and where Mailchimp, ActiveCampaign, or Klaviyo might serve you better.
That makes it valuable for businesses that want marketing and CRM data to support each other instead of living apart.
HubSpot email marketing is useful when campaigns, deliverability, and A/B testing need to sit inside the same system as the customer record. It helps teams manage email work with more context and a cleaner link to pipeline outcomes.
Email Types in HubSpot
HubSpot has three distinct email types, each with different use cases:
- Marketing emails: Mass emails sent to lists – newsletters, campaign sends, product announcements. These use HubSpot’s shared sending infrastructure (or your connected sending domain). Subject to CAN-SPAM/GDPR compliance requirements, unsubscribe links, and HubSpot’s anti-spam policies.
- Automated emails: Emails triggered and sent by workflows – nurture sequences, welcome emails, re-engagement campaigns. Same infrastructure as marketing emails but sent individually as triggered by workflow enrollment.
- 1:1 sales emails: Emails sent from a rep’s connected inbox (Gmail or Outlook) through HubSpot. These appear to come from the rep’s personal work email, not a marketing domain. These bypass marketing email compliance requirements (no unsubscribe link required) but are intended for individual prospecting, not mass campaigns.
Sending Domain Setup
By default, HubSpot sends marketing emails from HubSpot’s shared sending infrastructure. For professional deliverability and brand recognition, connect your own sending domain: Settings ? Marketing Email ? Sending Domains. This requires adding DNS records (DKIM, SPF, DMARC) to your domain’s DNS settings. Once verified, your emails will come from yourname@yourdomain.com rather than a HubSpot address, and DKIM signing will improve deliverability.
Set up DMARC on your domain – this tells receiving mail servers how to handle emails that fail SPF/DKIM checks. DMARC prevents spoofing and is increasingly required by Gmail and Yahoo for bulk senders. Configure it in your DNS as a TXT record: v=DMARC1; p=quarantine; rua=mailto:yourdmarc@yourdomain.com
Building Emails in HubSpot
HubSpot’s email editor is a drag-and-drop builder – similar in capability to Mailchimp’s editor. You can build single-column and multi-column layouts, add images, buttons, dividers, and dynamic content blocks. The template library provides pre-built layouts that match common email types (newsletter, product announcement, event invitation).
Personalisation tokens: Insert contact properties directly into email subject lines and body: {{ contact.firstname }}, {{ contact.company }}. Set a fallback value for contacts where the property is empty (“Hi there” instead of “Hi [blank]”).
Smart content: Show different content blocks to different audience segments within the same email. A contact in the US sees US pricing; a contact in EU sees EU pricing. Smart content is available at Professional and above.
A/B Testing
HubSpot email A/B testing (Professional+) allows testing subject lines, from names, email body, and send time. Configure A/B tests: set the split percentage (50/50 or weighted), the winning metric (open rate or click rate), and the test duration (after X hours or manually select winner). The system automatically sends the winning version to the remaining audience after the test period. Test one variable at a time. Subject line tests are the highest-leverage – a better subject line improves opens regardless of content quality.
Deliverability: What Actually Affects Your Inbox Rate
Deliverability in HubSpot depends on:
- List hygiene: Hard bounces (invalid email addresses) damage your sender reputation. HubSpot automatically suppresses hard bounces after one occurrence, but you should proactively clean lists before importing from external sources. Remove addresses not engaged in 12+ months.
- Engagement rate: Gmail and other providers track what percentage of your recipients open, click, or mark as spam. Low engagement rates cause inbox filtering. Segment your sends to engaged contacts and suppress non-openers before large sends.
- Unsubscribe rate: High unsubscribes signal irrelevant content. Keep unsubscribes below 0.5% per send. If you’re above that, the content or targeting is off.
- Spam complaints: HubSpot automatically suppresses contacts who mark emails as spam. High spam rates (above 0.1%) will trigger HubSpot’s compliance review and can result in sending limits or account suspension.
Email Subscription Management
HubSpot’s subscription management allows contacts to opt out of specific email types rather than all email. Create subscription types (Settings ? Marketing Email ? Subscription Types) for each category of email you send: Newsletter, Product Updates, Sales Outreach. Add subscription preference language and an unsubscribe link to all marketing emails. Contacts who unsubscribe from one type continue to receive other types – improving retention compared to a single all-or-nothing unsubscribe.
Where HubSpot Email Falls Short
- Design flexibility: The drag-and-drop editor is more limited than Mailchimp or Campaign Monitor for pixel-perfect custom templates. Advanced designers sometimes find the editor frustrating. Custom HTML email templates can be coded and imported as a workaround.
- High-volume senders: HubSpot’s sending limits depend on your plan and list size. Very high-volume senders (millions of emails per month) may find HubSpot’s email infrastructure less performant than dedicated platforms like Klaviyo or Braze.
- Transactional email: HubSpot is not designed for transactional email (order confirmations, password resets, account notifications). Use a dedicated transactional email service (SendGrid, Postmark, AWS SES) for these.
Email Analytics
HubSpot tracks open rate, click rate, click-to-open rate (CTOR), unsubscribes, hard bounces, soft bounces, and spam reports per send. Compare performance against your historical average and industry benchmarks (B2B averages: ~22% open rate, ~2.5% click rate). Email performance reports are available on each email send’s detail page and aggregated in the Marketing Hub dashboard.
One caveat on open rates: Apple Mail Privacy Protection (iOS 15+) pre-fetches email pixels, inflating open rates for Apple Mail users. HubSpot’s open rate reporting is affected by this. Treat open rates as directional rather than precise, and focus on click rate and downstream conversion as more reliable engagement metrics.
Getting your team to consistently use HubSpot
Adoption gaps occur when teams revert to old habits after initial training. Fix: Identify the 2-3 daily workflows where HubSpot adds the most value for your specific role. Focus training on those workflows first. Use HubSpot in-app guidance to provide contextual help at the moment of need rather than relying solely on one-time classroom training.
CRM data quality degrading over time
CRM data decays at approximately 30% per year as contacts change roles and companies. Fix: Schedule a quarterly data quality audit. Use HubSpot deduplication tools to merge duplicate records. Establish data entry standards enforced through validation rules. Consider a data enrichment tool like Clearbit or ZoomInfo to update stale records automatically.
HubSpot reports not matching actual business results
Reports are only as accurate as the data entered. Discrepancies between CRM reports and actual revenue indicate data entry gaps. Fix: Audit closed-won records against actual invoices monthly. Make CRM data the source of truth for commission calculations so reps have a direct incentive to enter accurate data.
Is HubSpot easy to learn for beginners?
HubSpot has a learning curve, but its official free training platform HubSpot Academy provides structured paths from beginner to advanced. Most users handle day-to-day tasks within 2-4 weeks. Admin and developer skills take 3-6 months to develop proficiently.
What are the biggest HubSpot mistakes to avoid?
Top mistakes include: over-customizing before understanding your process, skipping user training, importing dirty data without cleansing, and not establishing naming conventions. Avoid these four and your implementation will be significantly more successful.
How often does HubSpot release new features?
HubSpot releases major updates quarterly and ships smaller updates continuously to all tiers.
Does HubSpot offer customer support?
Yes. Support is available via chat, email, and phone depending on your plan tier. Enterprise plans include dedicated customer success managers. HubSpot Academy and the HubSpot Community are also excellent free support resources.
Can HubSpot integrate with other business tools?
Yes. HubSpot App Marketplace has 1,500+ integrations including Gmail, Slack, Zoom, Shopify, and WordPress.
The best email setup is the one that lets the team learn and improve quickly. If testing and deliverability are not monitored closely, the channel loses effectiveness.
