Spike

What Spike is

Spike presents email like a messaging thread instead of a formal letter. Conversations, files and notes sit together, several accounts share one inbox, and AI helps draft or summarize.

It is an email client rather than a marketing automation tool.

What you can do with it

• Read and reply to email as a conversation
• Unify several mailboxes in one inbox
• Draft or summarize messages with AI
• Share context with teammates in a thread
• Use a free allowance of AI queries

Who it is for

• Teams living in shared inboxes
• Sales and marketing staff handling enquiries
• Founders managing several accounts
• Operators who dislike formal email threads

What to watch out for

• Brand tone, platform rules, outreach compliance and attribution need checks when email is used for campaigns
• Email storage and access permissions matter with unified accounts
• Conversational layout changes how records are archived
• AI drafting still needs review before sending
