Instantly

Shared mailbox rotation could expose sender reputation to other users' poor practices; domain reputation can degrade rapidly if co-users violate sending norms

Email as primary channel faces declining effectiveness; spam filtering improves and email open rates decline generally
Lead database quality varies; verification filters may miss invalid addresses or outdated contacts
Freemium model limits features significantly; advanced analytics, API access, and priority support require paid tiers

Mattermost

No prices are published for any of the three paid tiers (Professional, Enterprise, Enterprise Advanced); all require contacting sales
Professional is capped at a maximum of 250 users, forcing a move to Enterprise for larger teams
Licenses are sold only as prepaid annual subscriptions, and organizations that exceed their licensed seat count must purchase additional seats on a prorated quarterly basis
