Record: https://feature-ledger.lehmanrylan790521.chatgpt.site/services/thunkmail/#thunkmail-starter-automation ## Keep the sending window beside the allowance Thunk Mail counts Starter and Base sends over a rolling 30-day window. Room comes back as old sends drop out of the window. A new calendar month does not reset anything, which affects how you plan a launch or repeat campaign. Source: https://www.thunkmail.com/help-center/plans-and-send-limits On Starter, total sends and the number of different people you email are separate limits. Deleting old contacts and importing new ones may not let you reach more people in the same window. Check the unique-recipient, daily, and hourly limits as well as the contact limit. - Thunk Mail Starter, sends: 5,000 / rolling 30 days. Also limited to 500 different recipients per rolling 30 days, 1,000 sends a day, and 500 sends an hour. Campaigns and autoresponders share these limits.

Record: https://feature-ledger.lehmanrylan790521.chatgpt.site/services/thunkmail/#thunkmail-starter-contacts ## A welcome email and a sequence need different plans If your signup only needs one welcome email, a one-email autoresponder may be enough. A course or multi-day onboarding sequence needs more emails in the autoresponder. List those messages before choosing a plan. - Thunk Mail Starter, automation: 1 email / autoresponder. This counts emails in each autoresponder, not workflows. Autoresponder emails use the normal sending allowance.

Record: https://feature-ledger.lehmanrylan790521.chatgpt.site/services/kit/#kit-creator-automation Thunk Mail's autoresponder emails use the same sending allowance as campaigns. For example, four messages to 300 people use 1,200 sends. Add your broadcasts before deciding whether the allowance fits. This math measures volume only. It doesn't mean the two providers' workflow tools are equivalent.

Kit's Creator price is a yearly commitment at a set subscriber tier. Match the billing term and list size before working out which plan costs less.

Sending to a list requires a paid plan. Its hosted signup forms ask subscribers to confirm before adding them to the chosen lists. Source: https://www.thunkmail.com/help-center/plans-and-send-limits Source: https://www.thunkmail.com/help-center/collect-signups-with-a-form Use your own test addresses to try signup, confirmation, the welcome email, a scheduled campaign, and an unsubscribe. If you need branching, event triggers, paid-newsletter tools, or an integration, check for that exact feature. Unlimited emails per autoresponder does not mean every automation feature is included. ## Common questions ### Does Thunk Mail offer a free sending plan to new accounts?

Source: https://www.thunkmail.com/help-center/plans-and-send-limits ### Is Thunk Mail Starter limited to one autoresponder? No. Starter allows one email in each autoresponder.
