As often as she is writing back, and no more than that. There is no correct number per day, and men who go looking for one are usually trying to solve a different problem with arithmetic. Match her rhythm, keep it moving while she is engaged, and get to a plan within a few exchanges instead of settling into a pen pal arrangement.

Why the number is the wrong question

The question assumes she is keeping score. She is not. Nobody is sitting with a tally of how many times you wrote on Tuesday.

What she does notice is shape. Whether you write back roughly as often as she does. Whether your side gets longer as hers gets shorter. Whether anything is being built or the two of you are just taking turns.

A man who sends four a day to a woman doing the same is not being too much, he is being matched. The same four a day, to a woman answering once every evening in one line, reads completely differently, and the number did not change.

Match her rhythm, do not set your own

The simplest rule that works: roughly her frequency, roughly her length, roughly her energy.

If she writes two lines, write two, not eight. If she takes five hours, you do not have to take five hours back, but you should not be answering in nine seconds every single time either. If she uses three exclamation marks, you can loosen up. If she is dry and short, match dry and short and see whether it warms.

This is not a game and it is not about withholding. It is about reading how much she wants to invest right now and investing about the same. Overshooting her by a wide margin is the most common error, and it is read as need rather than as interest.

The first day after you connect

Speed helps most at the very start, and matters less afterwards.

Answer a new person within a few hours if you can. Attention on the apps is short, and a page she liked on Tuesday is somebody she may not remember by Friday. Two or three exchanges in that first stretch is a healthy pace for new matches.

What does not help is six in a row while she is at work. The goal on day one is a real back and forth, not proof of enthusiasm.

Why double texting reads the way it does

One follow up into silence is normal and mostly harmless. Three is a different signal entirely.

Sending again before she has answered tells her your side of this is running on its own, independent of whether she is participating. It also hands over information you would rather keep, which is how much you want it. A man who can leave a gap alone reads as a man with other things happening.

If she has not answered in a day or two, the move is not another attempt at the same conversation. It is one light message that gives her a fresh thing to respond to, or nothing at all. Both beat a stack of unanswered lines sitting there when she does come back.

The exchange exists to set up a date

Here is the part the frequency question usually hides. A lot of men want to know how often to write because they are planning to keep writing indefinitely, and that is the actual problem.

Four or five exchanges is normally enough to know whether you want to meet. Around there, name a place and a rough day. If the typing goes past a week with no plan in it, the odds drop steadily, because the two of you have settled into a habit of talking rather than a run up to meeting.

Long conversations feel productive. They are usually the opposite. They build an idea of you that a real evening then has to compete with.

Once a date is set, go quiet on purpose

After she has said yes, the job changes. You are no longer building interest, you are protecting it.

A little contact is good. Something small the day before, a confirmation of time and place, maybe one thing that made you think of her. Daily updates for six days are not good. They spend the material you would rather use in person, and they let her get bored of a man she has not met.

If the date is more than a few days out, one or two touches across the whole gap is plenty.

When the frequency is not really the problem

If every conversation dies regardless of how often you write, pacing is not what is wrong.

Look at the openings instead. If they die in the first two exchanges, whatever you are sending first is not giving her anything to work with. If they die right after you suggest meeting, the ask is arriving too early or with no actual plan attached. If they die at exchange fifteen, you waited too long and the whole thing went stale.

Each of those has a different fix, and none of them is a better answer to how many times a day. Work out which point yours die at, and start there.
