Questions

Something else? Write to us and a person will answer.

  • Both. Use sequences to reach new buyers, and campaigns and flows for people who opted in. Both share one contact record.

  • No. WhatsApp requires opt-in. Syntr moves a conversation to WhatsApp after the person agrees, for example after a positive reply or a form.

  • Syntr warms new mailboxes, spreads sending across mailboxes and pauses sending when bounces or complaints rise. No tool can guarantee the inbox, but these steps protect your domain.

  • An AI-written email costs 1 credit per person; researching a lead costs 1 credit; translating a campaign costs 2 credits per language. Template emails use no credits. Top-up credits never expire.

  • Shopify, Slack, Google Meet, Apollo (bring your key), webhooks and an API today.
