Why buyers keep looking beyond Mailgun
Lacks visual email builder — teams prioritizing design-heavy campaigns typically switch to Mailchimp or ActiveCampaign
Missing integrated CRM — businesses needing contact management and lead tracking in one platform often choose HubSpot or Zoho Campaigns instead
Requires developer resources — non-technical teams find implementation and ongoing management difficult without engineering staff
No pre-built email templates — users wanting ready-made designs or polished UI switch to design-focused platforms
Limited workflow automation — lacks behavioral triggers and segmentation features available in Klaviyo or GetResponse
Support tiers restrict access — real-time support only at higher plans, pushing smaller companies toward vendors with inclusive support at all levels
