I would 1st change the commas and blanks that don't belong to the string into newlines so that every string is on a separate line and then pipe them into a while/read loop, where I can do something with every single line that is being processed:

Code:
$> cat infile
aaa, bbb, ccc, ddd dd, eee, fff, ggg gg
$> sed 's/, /\n/g' infile| while read LINE; do echo bla "${LINE}"; done
yo aaa
yo bbb
yo ccc
yo ddd dd
yo eee
yo fff
yo ggg gg

As example I just added that "bla" in front of every read line. You can do something else inside that while loop that would make more sense of course. If it is just for formatting text you could maybe just do it all in sed or awk etc.

smd-loop

smd-loop(1)						 Sync Mail Dir (smd) documentation					       smd-loop(1)

NAME

       smd-loop - iterates smd-pull and smd-push

SYNOPSIS

       smd-loop [-vt]

DESCRIPTION

       smd-loop  runs  smd-push and smd-pull at regular intervals as defined by the user in the ~/.smd/loop configuration file. On errors that are
       reported to be transient, it retries a second time before failing.

       The configuration file is line-oriented. Each line is composed of three space separated fields:	pull-frequency,  push-frequency  and  end-
       point-name. Frequencies are expressed in minutes, while endpoint name is a valid name for smd-pull(1) and smd-push(1). Lines beginning with
       # are considered as comments. The following example calls the command smd-pull default every 3 minutes,	and  smd-push  default	every  10.
       Example:

	   # pull-frequency push-frequency endpoint-name
	     3		    10		   default

OPTIONS

       -v     Increase program verbosity (printed on stderr)

       -t     Just create a template configuration file if none

FILES

       ~/.smd/loop

SEE ALSO

       mddiff(1), smd-server(1), smd-client(1), smd-push(1), smd-pull(1)
