❓ Frequently Asked Questions
What email platform is best for marketing teams?
HubSpot for teams that want CRM + email in one. Klaviyo for e-commerce marketing teams. ActiveCampaign for automation-heavy teams. Marketo for large enterprise marketing teams with a dedicated ops person.
How do marketing teams manage email deliverability?
Use dedicated IP addresses (available on enterprise plans), maintain clean lists (remove bounces and inactives regularly), authenticate domains (SPF, DKIM, DMARC), and monitor deliverability with tools like MXToolbox.
What A/B tests should marketing teams run on emails?
Highest impact tests: subject line (open rate), send time (open rate), CTA copy and placement (click rate), personalization (name vs. no name), email length, and image vs. no image. Test one variable at a time with enough volume.
How do marketing teams measure email ROI?
Track revenue attribution by connecting email clicks to purchases/signups. Calculate: (Revenue from email - email tool cost) / email tool cost = ROI%. Top teams also track list growth rate, unsubscribe rate, and email-attributed pipeline value.
