**(40) How can I reduce the data usage of FairEmail?**
You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

**(161) Can you add a setting to change the primary and accent color?***
If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

**(161) Can you add a setting to change the primary and accent color?***
If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.

It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

**(161) Can you add a setting to change the primary and accent color?***
If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

**(161) Can you add a setting to change the primary and accent color?***
If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).

Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(

**(161) Can you add a setting to change the primary and accent color?***
If I could, I would add a setting to select the primary and accent color right away, but unfortunately Android themes are fixed, see for example [here](https://stackoverflow.com/a/26511725/1794097), so this is not possible.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed.

You can reduce the network usage basically in the same way as reducing battery usage, see the previous question for suggestions.
You can reduce the data usage basically in the same way as reducing battery usage, see the previous question for suggestions.
It is inevitable that data will be used to synchronize messages.
If the connection to the email server is lost, FairEmail will always synchronize the messages again to make sure no messages were missed. If the connection is unstable, this can result in extra data usage. In this case, it is a good idea to decrease the number of days to synchronize messages for to a minimum (see the previous question) or to switch to periodically synchronizing of messages (receive settings).
By default FairEmail does not download message texts and attachments larger than 256 KiB when there is a metered (mobile or paid Wi-Fi) internet connection. You can change this in the connection settings.

**(160) Can you add permanent deletion of messages without confirmation?**
Permanent deletion means that messages will *irreversibly* be lost, and to prevent this from happening accidentally, this always needs to be confirmed. Even with a confirmation, some very angry people who lost some of their messages through their own fault contacted me, which was a rather unpleasant experience :-(
