Watchouts

Reasons buyers look elsewhere

Moosend

Lacks advanced automation workflows — teams needing complex multi-step sequences often switch to HubSpot or ActiveCampaign
Price-sensitive buyers find cheaper alternatives like Mailchimp or Klaviyo that cover basic email marketing at half the cost
Limited onboarding and support — companies wanting hands-on training or dedicated account management choose platforms with stronger customer success teams

SMTP

Users may seek alternatives to SMTP due to deliverability issues, as emails can often be marked as spam or face filtering challenges, impacting communication effectiveness and business operations.
Security concerns are a common reason for exploring alternatives; SMTP lacks advanced encryption and authentication measures, making it vulnerable to interception and unauthorized access.
The increasing need for real-time communication drives users towards alternatives that offer instant messaging or collaboration features, which are not supported by traditional SMTP protocols.
