Instead of “I will follow up with you,” you can say “I’ll get back to you,” “I’ll check in with you,” or “I’ll send you an update.” The best phrase depends on whether you are promising a reply, an update, a reminder, or a later conversation.

I’ll get back to you
The most natural option when you need time to check something before replying.
Example: I’ll confirm the figures and get back to you this afternoon.
I’ll check in with you
Useful when you plan to contact someone later to see how things are going.
Example: I’ll check in with you next week to see how the rollout is progressing.
I’ll send you an update
Best when you expect to have new information to share.
Example: I’ll send you an update once the decision has been made.
I’ll be in touch
Broad and professional when the exact form of contact does not matter.
Example: I’ll be in touch when we have the final schedule.
I’ll contact you again
Direct and clear, though slightly more formal than “I’ll be in touch.”
Example: I’ll contact you again after I’ve spoken with the supplier.
I’ll come back to you on this
Common workplace wording, especially in British English, for returning with an answer or decision.
Example: I’ll review the proposal and come back to you on this tomorrow.
I’ll let you know
Simple and natural when the follow-up will contain a specific answer or outcome.
Example: I’ll let you know as soon as I hear back.
I’ll keep you posted
Informal and useful for ongoing developments rather than a single reply.
Example: I’ll keep you posted as the plans develop.
I’ll follow this up
Focuses on taking action on the matter, not just contacting the person.
Example: I’ll follow this up with finance and let you know what they say.
I’ll reach out again
Natural in some professional contexts, particularly American English, but more corporate-sounding than “I’ll get back to you.”
Example: I’ll reach out again once the dates are confirmed.
