The Verdict
Spark is built for professionals and small teams, with a focus on smart-inbox and ai-writing. Tettra targets growing teams and ops teams and leads with ai-answers and slack-bot.
Both tools come in at similar price points ($7.99/mo for Spark, $8.33/mo for Tettra), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
