AFAIK you can use Segwit addresses starting with a 3 in Electrum.
That's what you need to do:
to have segwit addresses starting with a 3 in Electrum just follow these simple steps:
1) generate a bip39, 12 words seed on
https://iancoleman.io/bip39/ (use it offline for more security)
2) on electrum choose, File -> New/Restore -> Standard Wallet -> I already have a seed -> click on "options" and choose bip39, write the seed then click next
3) on derivation path path use:
m/49'/0'/0'/0that's all. Remember to save in a safe place the seed as electrum will not show it (read below)
some wallet or exchange may not able transfer to your address?
Most major services still don't support addresses with the bech32 format.
